There is one coming up in November in Atlanta. It is expensive ($300) and during school (Thur and Fri). I have heard the ones in CA and CO are well attended by college coaches, but have no idea what to expect in GA.
Today was the first day of the OnDeck East Coast National Elite Camp in Atlanta. There are two team showcases in town this weekend (Southern Force in Watkinsville and Champions in Marietta) so there are a lot of college coaches in town. There were 30+ college coaches in attendance during the pitching sessions. The SEC and ACC were very well represented. The camp is very well run, but got behind and the weather was much cooler than it has been. Temperatures went from chilly to downright cold after the sun went down. At 7pm the lights on the field went out and my DD and I decided not to wait around until they got them back on since we had been there for almost 12 hours. Tomorrow they break into teams and play a couple of scrimmage games. I recommend going if you get the chance!
