My family attended Austin's big night this evening and had a great time. There were hundreds of people that showed up, the band was excellent, they did photos of everyone and Austin was so, so happy. He's a great, goofy young man!
A few pics from the evening:

He just got back from seeing his very best friend in Montana for a few days. He is taking Victoria out for Valentines (just as friends so neither of them is alone), and then he is taking the Amtrak to Chicago to visit another close friend for a few days.
His parents were happy, but cracks showed up occasionally as is expected. While he's managing at the moment, they hope he can make his 21st Birthday in April.
Thanks for all who've asked for updates.
