Kathik and TowPro, please do consider coming anyhow. The dirt roads of Michaux are almost groomed, they are so easy to ride. I drove a lowered Miata through it all from Mt Holly Springs to Waynesborro on Ridge Rd. The north end is rougher, but hey, I drove a Miata through it!
As for speed, I'm going for a ride to look at pretty colors and such, not a race. The speed limits are pretty low in the park anyhow, and I don't feel like collecting tickets. If some speed demons take off and leave me (us) in a cloud of dust, so be it.
The idea is a scenic ride, not a race. With some destinations along the route that folk have said are worth stopping at to admire.
