Rumbling Bald, Cereal Buttress great, classic, gneiss cracks. in beautiful gneiss rock. some stuff on the East Face of Table Rock, in Linville Gorge. Also, in Linville, the ampitheatre has a few classic crack climbs in a wilderness setting you wont find anywhere else. Looking Glass also has some beautiful cracks. and a piss ton of small flared horizontal ones. (the infamous eyebrows)
the new has some great cracks too, but i'm impartial to NC.
