Last Saturday, Josh and I went to the Moab Pumpkin Chuckin festival. The event is put on to raise money for the Youth Garden Project (an amazing garden that high schoolers keep with an amazing amount of plants and also some chickens) and featured a bunch of sling shots and trebuchets and catapults.
There were some very large contraptions that threw the pumpkin very high and sometimes very far... but the ultimate goal was to hit a target that they got to place out in a field. It was a lot of fun to watch, and I've loaded a couple of videos onto Flickr, so feel free to take a peek!
These guys (the Bluff Whipper Snappers) managed to hit their target all three times. The kids helping out had a windsock to see which direction the wind would take the pumpkin, and set it off with a machete.
