Is it 'Punkin' Chunkin' or 'Pumpkin Chuckin'?

We're off to watch some 'punkin' chuckin' today... I'll try to get some pictures but my guess is I'll end up with a lot of shots of a big empty field surrounded by a LOT of people.

Hope this is going to be fun!!! I'm currently fighting a raging head cold, sore throat, head-ache, runny nose... So I figure, what the hell... Why not drive 2 hrs. to stand in the middle of a cold and windy field to watch some asshole shoot a pumpkin out of a cannon... See, I'm excited already!
