I camped and biked at Kerr Scott this past May. I would highly recommend one of the tent only sites in the Bandit’s Roost campground. The loop we stayed on was tent only (sites A01 though A09) and the sites were awesome. You should be able to go to the camping reservation site and see the map for the campground and the loop I’m talking about. The sites were very large and relatively secluded from each other. They were also about 100 yds from the OVT trailhead. You can jump on that and take OVT all they way to the visitors center, then cross the dam and ride Dark Mountain. I’d load the bike on the car and haul it to Warrior Creek just to avoid the traffic on the hwy though.
