Plan your own baseball game. Don't just play baseball, but plan on creating the whole experience. During the "7th inning stretch" plan on having hotdogs, nachos, and ice-cold drinks. While the batting team is waiting, they can be enjoying cotton candy, peanuts (in the shells), garlic fries, etc. Create tickets that each teen can buy for $5.00 (to cover the food). It may be advisable to play "rag-ball" instead of baseball since it's easier to hit, doesn't fly as far, and doesn't require everyone to have a glove. Play ball!
