British Isles may be an answer, but it's not the only one. The Hartford area has a bunch, as Phil, Cliff and Tim mention. All those courses are alive and well. Other, formerly private, courses have opened their doors to the public.
HOWEVER, my brother-in-law from Insurance-Land just spent a week here in western New York and played four rounds at an RTJ, Sr., Hurdzan, and Muirhead (along with Links at Ivy Ridge) for half of what he would pay in CT. Buffalo has six legitimate upscale public courses that can be had for less than $35 on weekdays. Throw in at least 15 municipal courses and about 10 mom-and-pop designs and we stand up well against all comers. Rochester, NY has Ravenwood, Mill Creek, Greystone and at least 20 more privately-owned, public-access courses. All are economically priced and conditions are fine to excellent, especially given all the rain this Summer.
I've been to Charlotte and agree on it as a candidate; also with northern Michigan's candidacy.
