Robert (KLickeR) and I went yesterday on a ride and explored the horse pasture rd. There are spots where the gravel is too big, too much but other than that a very pleasant ride with beautiful scenery. Here's a link to the road
There's a little creek to cross (Creek crossing 101) to add to the fun. A word of caution: plenty of blind spots. We encountered many four wheel drive vehicles including a black F-150 driven by a teenager who just kept going as fast a he could, leaving just enough room for the bike to squeeze in going downhill with the cliff on our right.
Definitely worth bringing in your camera on this trip. Just say when Ridingman1
