There are a few things we have done over the last couple of years....as my daughter is now on a 13U travel softball team. Euchre tournaments are great, not exactly sure how they are set up but I know they raise good money. Bowling fundraisers are pretty good if you can get a bowling alley to offer up a few lanes. Last year her team did a comedy night with a restaurant that does stand up comedy. A new one that actually was pretty easy for us to sell was Football Mania. It's an on-line type of fundraiser where you sell tickets $20 with a chance to win all 17 weeks of football and 70% of the profits go back to the team. You can check it out along with some others at:

Hope that helps!!
