My sophomore year college roommates and I got along so well as random roommates put together by university housing, that we've stayed good friends since our respective graduations. About every two years, we get together somewhere in the country and hang out for a long weekend. First was Vegas, then Ft. Collins/Denver, Miami, Washington D.C. and now Charleston.
Charleston was a great choice from top to bottom. Beach, city and everything in-between plus C decided that a vacation rental would be the way to go - and we had a great house for the weekend on James Island - very centrally located.
Day 1 was spent at Folly Beach, in order to avoid the weekend crowds. The water was warm and we definitely spent the bulk of the day wave-jumping vs laying out and getting tan (or in my case, sunburned). I swear I applied the sunscreen liberally but alas, I ended up a little burnt on my nose and decently burnt on my shoulders and back.
