Mine was the Sacramento Regional in 2003.
Even though I later learned that it was a relatively small regional (28 teams) I thought it was amazing to see so many teams in one place. I've been to 7 competitions (5 local) and this one was the only competition my parents ever came to see. I just remember being really, really excited. I was even excited to start the practice rounds. I was the arm controller for Spicy Mustard (see attachment). We won the Leadership in Controls Award, which qualified us to go to Houston, and were semi-finalists. Oh, and I remember the FemBots (692) cheering a lot.
But most importantly, this was when I first became aquainted with
