Our organization covers baseball, slow pitch and fastpitch. The most games I've done in a season (baseball)is 140. This season being an all time low for me at 19 baseball and a dozen or so softball do to family committments I was only able to fill in where absolutely needed.
I'll read in to your question "your off to college and looking to make a little side $$?"
If thats the case it's a great past time and you can make some spending money. Our busiest official/s willing to work any, all, anytime, and anywhere near 5000.00 a season which runs from late April to early Oct. I've been at it for off and on 28 years, mixed in with 17 years of coaching and league administering, though coaching is my favorite (well after playing that is) Ump-n is next in line, best seat in the house and if done correctly a pretty good conditioning regime. I am very near to 47.
