i heard it was free to watch i wanted to take my kids to see them tryout /i'm not sure i heard it was some kind of camp

doesn't look like they've announced it yet but it was at Rams Park in Earth City the last few years...see the link for directions

There camp and workouts is at Western Illinois University in Macomb, IL. I know because a ton of my friends went there and right before school started up in the fall, they would go check out the team practicing on their field.

Macomb Illinois is wrong. Its in Earth City, MO
