If your OK with a roadtrip, Best of the Best in Cherry Hill NJ. It's just across from Philly. It's in Feb. I've been the last 2 years and it is unbelievable. The best NCAA coaches right at your fingertips. They are all very approachable as well. I can't think of a reason why I won't be back year after year.
Side note: A bunch of coaches from our organization were chewing on Ralph & Karen Weekley's ears, and one guy got Karen's email. He had some sort of question that he emailed her during the college world series that they were in at the time. He figured he'd hear back from her within the next couple weeks. That night that they played, and she replied after the game. What great people!!!! Go Vols!!!
