A friend and I went to spectate in 2005 and it wasn't a large event; just a huge farm field and a bunch of guys and gals competing to see who could throw 8-10# pumpkins the farthest in each of three categories: pneumatic cannon, trebuchet and catapult. Sure was fun to watch, though. Then there was an unofficial "accuracy contest" with the target being an old car. Amazing to watch a 10# pumpkin hit a car... Take some lawn chairs and food for the day, as I don't recall there being any food vendors, although maybe that's changed.
If you could locate the gal in WTM442's avatar, I'm sure she would be grateful for an opportunity to use your lift. Looks like she's got a lot of "lift" there already but apparently she needs "a lift".
