User name says it all. I work football, basketball and softball. Where I live there are no opportunities for very much fall or winter softball, so I work football and basketball.
Football is the most fun but also the most time consuming on a per game basis. A Friday night game gets you to the game site 1.5 hrs before the game, the game is 2.5 hrs and then to travel home after for around $60. Unless you do youth games, not a lot of dh's in football.
Basketball good excersise and a good way to train your game management skills.
