I just had my 08 son there at a prospect camp they held.
Nice field (although the dugouts are not that great). Oakland is a pretty good school academically. I don't know too much about their baseball team. The campus area was decent also.
The coaches seem OK. They put the kids through a pretty good instructional workout before the game. They didn't have any radar guns going during the workouts and I was a little surprised by that. But the one coach said that NCAA rules prohibited them from using the radar guns at that time.
