UNC Asheville, one of the relatively few public LACs, is worth a look. The core curriculum is noticeably more restricted than at SLC, but it has the vibe and students you’re looking for, I think. With 3800 undergrads, it’s on the larger side for a LAC.
Asheville itself is quirky and hip. Residents are pretty proud that it boasts more craft breweries than any city in the US besides Portland.
