Barnyard RV Park, Lexington, SC
Although we have nothing to compare it to yet we give 3.75/5 (once we've stayed at more we may come back and update this post)
We really enjoyed this place.
Pros: The staff was extremely friendly and check in was a breeze. The site was conveniently located close to amenities such as restaurants, gas stations and entertainment. The park itself was clean and the park bathrooms were the CLEANEST public bathrooms I ever seen. Of course it is within walking distance to the awesome Barnyard Flea Market so that is a major plus.
Cons: My biggest complaint is that there are no fire pits so that means no campfire. There are not a lot of amenities at the park itself (playground, trails, etc) but I suppose the major attraction is the flea market. However, since the flea market closes at 430 it would be awesome to have some options around the park for the rest of the evening. The site wasn't family friendly (things of interest to both parents and children).
Overall, we would definitely stay at this RV park again.
