Knobby Creek is no more, they had a big farewell event in the fall, I think the owner sold the property. Shame, it was really well done, but they also stopped hosting comps and such around the time I first went. They clearly put a lot of time into it. It was really fun and they had a race track also, really well thought out and the owner was super nice, but the location was kinda rough getting to.
Dark Hollow in SC is on hiatus as well, I never made it there, but he said it's closed for the foreseeable future, although not permanently like Knobby Creek.
There was another guy in Asheville who had stuff on his property but he gave up about a year ago to do oval.
There are groups in Greenville that go to Falls Park, Caesar's Head, and Glendale Shoals, but they announce events on FB groups, of which there are probably a dozen and it's impossible to keep up with.
Eastern TN has a few areas, there are some folks in the Knoxville area that are somewhat active on FB, they have some cool terrain along the highway near the river and I know they hosted a comp there this past weekend.
The hurricane re-routed parts of the Davidson River, which moved a lot of rock into weird spots it wasn't before, this is probably the most rock in one spot that I've found in this area but I haven't explored how easy it is to get to. This is down by the fish hatchery.
TBH it kinda seems hard to win with the crawling scene here. I think there is interest, but none of the public areas I've been to have any kind of rock features like what you see in areas out west or where comps take place regularly in VA and LA. Hosting events in either Pisgah or Dupont require permits and they'd flat out reject anything related to this. It would take someone with the land and people willing to build/invest in it: buy rock, rent equipment, and help build. I'd do it here where I am, but our usable land is too steep to do any kind of rock work.
We have so many trails, that part is covered, so I'd really like to see a dedicated area for it.
