Stay away from Rock Hill if at all possible. I lived there 30 yrs ago in high school and still have friends and family so I visit often. It is a fast-food, ignoramus-ridden, nothing-happening kind of place. If you can get a home on Lake Wylie with easy access to Charlotte it might be liveable, but the closest thing to culture there is the kitschy kountry krap you can buy at the counter at Cracker Barrel.
If you like smoky bars full of ugly women and depression, be my guest.
Oh yeah, you CAN'T BUY ALCOHOL ON SUNDAY IN SC so Saturday night at 12 things shut down. HEATHENS, I tells ya!
And Rock Hill is considered civilized compared to the surrounding SC towns.
