Im not sure on the total head count, but the line has a full 40 shooters on it, plus myself and appleseed staff. I would GUESS 55ish. There is enough people I thought about asking the local fire department if they wanted to sell burgers or ? but I would hate for them to put the money into it, and end up losing money.
I bet the burger thing would go over well... especially if they did it on Sunday and you let everyone know on Saturday that a fire department or boyscout troop or whatever was going to use the opportunity to raise a little money. That type of thing would fit right in with the essence of Appleseed.
Either way, this sounds like a great time! I haven't had much time for shooting this summer, so I'm glad I'll get a chance to knock some of the dust off my rifles.
