That site tells you most everything you want to know. They have games in FL, AZ and elsewhere....
I've worked for them for 5 years - they have everything from NAIA to Juco to D1, D2, and D3. You can go for a few days or 6 weeks.
The pay isn't great but it's a great start getting out there on the field, seeing some plays and pitches and gettin' some sun.
