I've been volunteering since my senior year of high school (2000-2001). -Started off with FLL field reset that year
-Moved to FRC team queuing for the 2002 Philly and 2003 Richmond regionals
-Event assistant at 2003 Philly regional
-2004 Richmond regional was team queuing some, but a lot of what I like to call running around making sure everything runs smoothly work
-2004 and 2005 (and 2006) Philly regional was/is assistant to the regional coordinators (job invented for me), which is basically a combination of setup, take down, talking to VIPs, running around making sure everything runs smoothly, answering questions, and just generally having fun
There's a few more FLL tournaments in there, judging for the ones here in PA and field manager for one in Richmond.
I love my job, even if it is VERY tiring. It's my run-around and always look like I know what I'm doing thing
I highly recommend volunteering, it's a very different perspective from being a team member or even a mentor, very eye-opening, and rewarding, IMHO!
