Ok… this paints an entirely new picture for me… wow
• The daughters of former Texas Govs. Dan Moody, Price Daniel, and John Connally, who was shot as he sat next to President John F. Kennedy when he was assassinated in Dallas in 1963, all attended the camp.
The daughters, granddaughters, and great-granddaughters of Democratic President Lyndon B. Johnson — JFK’s successor and one of Texas’s most formidable politicians — also summered at Camp Mystic.
• James Baker, who served as chief of staff to Republican Presidents Ronald Reagan and George H.W. Bush, sent his daughter and a granddaughter to Camp Mystic.
• First lady Laura Bush was a Camp Mystic counselor, years before she married George W. Bush
• Campers would go on to “become executives for Neiman Marcus, dance with London’s Royal Ballet, own a Gymboree franchise in the former Soviet Union, or marry well and become the kind of intensely focused volunteers who would probably be happier as CEOs,”
• Aside from when the federal government leased Camp Mystic as “a convalescent camp for Army Air Corps veterans of World War II” between 1943 and 1945, it has operated continuously since its founding, according to the Texas State Historical Association.

Active Evacuations & Flood Alerts Across Texas
Central Texas – Guadalupe River BasinKerr & Comal Counties
Widespread mandatory evacuations are in effect near the Guadalupe River, including riverside neighborhoods and low-lying camp sites. Over 800 people have already been evacuated from these areas.
Evacuation centers have been set up in Kerrville, Ingram, Comfort, and Spring Branch to assist displaced residents.
A FLASH FLOOD EMERGENCY continues for Marble Falls TX, Granite Shoals TX and Liberty Hill TX until 7:00 PM CDT. This area which is just NW of Austin has picked up 10-20" of rain today. 
Georgetown / Williamson County – San Gabriel RiverEvacuation orders cover Riverside Mobile Home Park, Shady River RV Park, Goodwater RV Park, Two Rivers Apartments, San Gabriel Apartments, and Waters Edge Apartments. Shelters are open at East View High School and Georgetown Recreation Center.
Flash Flood Watch and Warning remains active; the San Gabriel River is nearing a projected crest of ~29.7 feet, well above flood stage.
New Braunfels / Comal CountyNo mandatory evacuation for New Braunfels city itself, but precautionary evacuation advisories are in place for low-lying riverside areas along the Guadalupe River upstream of Canyon Lake.
Residents in vulnerable flood-prone zones are urged to move to higher ground immediately.

BREAKING: An incredible "gigantic jet" – an extremely-rare type of upper-atmospheric lightning – was photographed from the International Space Station on Friday morning.
This is the clearest photo we have EVER seen of a gigantic jet from above.
Nichole Rhea Ayers is a major in the U.S. Air Force and a NASA astronaut. She launched to the International Space Station as a pilot of the SpaceX Crew-10 mission on March 14, and will be returning to Earth soon.
On Thursday morning, July3, she captured an unbelievable photo of an ultra-rare GIANT JET. The International Space Station was over Mexico and the southern U.S. at the time.
It looks like the instigating thunderstorm was happening somewhere near Sabinas in Coahuila, Mexico around 1:30 a.m. Central time Thursday.
Gigantic jets are a subset of “blue jets,” which themselves are a type of TLE — or transient luminous event, often referred to as “upper-atmospheric lightning.” There are different types of TLEs, including red “sprites,” green “elves” and blue jets.
Blue jets are the rarest. Elves and sprites occur high above thunderstorms, but jets bridge a key gap between a thunderstorm and the stratosphere high above. Sometimes they even reach up to the base of the mesosphere — the height at which meteors burn up!
They begin as a cloud-to-air discharge that emanates out the top of thunderstorms, but immediately grow to MASSIVE sizes — up to 30 miles tall! They shoot upwards at speeds of 6 to 90 miles PER SECOND, but only last two or three tenths of a second. They are bright blue (almost like a neon sign, since they are plasma after all). The blue color is believed to stem from “excited” nitrogen.
It’s believed that blue jets start as an ordinary lightning strike in the top of thunderclouds, where abundant positive charge is present. Sometimes there’s a negative charge in the clear air above. Instead of the negative charge flowing down to balance out the positive, sometimes the positive shoots upwards into the clear negative skies above. The result? A positive discharge that propagates upwards.
Gigantic jets are even more spectacular. Emerging research suggests they begin as a discharge between negative charge in the mid-levels of the cloud and the positive tops of clouds. That leads to a *negative* “leader” of electricity that shoots upwards and escapes the cloud before it can actually discharge and “balance out” charge within the cloud.
You can tell this one was a “gigantic jet” because of the reddish tops that resembles the stem of a carrot. That’s a sign the gigantic jet reached even higher altitudes — perhaps 50 to 60 miles above the ground.
Atmospheric electrodynamicists (the fancy term for folks who study lightning) are learning about all sorts of never before-discovered lightning discharges. Most of what we know comes from photos like this! In recent years, scientists have coined new terms for curious, fleeting discharges — “trolls”, “pixies”, “ghosts” and “gnomes”.
The existence of upper-atmospheric wasn’t known until July 6, 1989, when a researcher named R.C. Franz left a camera running overnight to capture the night sky. For decades, pilots had reported seeing strange red and blue flashes above thunderstorms, but it wasn’t until Franz obtained photographic evidence that scientists were able to delve deeper into the mystery.
Nowadays, most of what we know comes from photographers who happen to get lucky — especially since the flashes usually last only a couple milliseconds. Ayers’ photo is truly a one-of-a-kind capture that will hopefully shed more light on how TLEs behave.
