You've been to the one in Durham, how about the one in Kannapolis? I lived there summer 1995, shortly after it was built (they put a clock tower in, but forgot to put arms on the clock, IIRC). I think it was AA for the Phillies at the time. Looked really nice from the outside (and via a peek inside), but I never made it out to a game. Only been to one minor league game, and that was in Round Rock, when it was AA. I think they were playing LA's team from San Antonio. I just remember Lugo was on the squad, and Michael N was at the game with me, and had mixed things to say about Lugo.
Good time.
Went to a college game up there at the same ballpark, too. USC vs. someone... gruesome experience on-field, though, as the 3B and RF collided and you could hear a bone (femur?) snap. That side of the field (I was 3rd row back on the 3B side) was feckin' COLD in the shade, and then blazing hot when the sun game out. Not so good of a time.
