YES!!!! My daughter does competitive cheerleading. They travel all over the country for competitions. Without this fundraiser we could never afford it. We are just outside of Detroit so we do Comerica Park with the Detroit Tigers. I can't tell you how easy it is and how much fun we have. We have been in booths selling everything from beer and brats, to Dippin Dots, to snow cones and lemonade. We work concerts, too. This Sunday I'm working the Paul McCartney concert. In August we are scheduled to work for the Kid Rock concerts. We have a blast and pay for almost the whole season with the funds. Easy, easy money. Definitely worth checking out.
I will definitely look into this, the only thing I worry about is our team is 10 year old boys and under. I'm thinking there will be restrictions on letting them work the concession stands especially if they sell alcohol. The parents may get together to do this but I think it is important for the kids to understand the hard work involved to "earn" their tournament trip. Great suggestion, I've worked the concession stand before to help out a non profit organization in the area and can't remember if they got a percentage of sales or how that worked.
