Don't know if any of you ride the "Diamondback", aka Little Switzerland, AKA 226a, but wanted to pass this info on. The DOT has repaired the road with "tar snakes", the stuff they use to fill in cracks instead of paving.
On straight surfaces it's scary, add in braking, turning, and elevation changes it is terrifying. I brought along a guy on his FZ1, track rider and very experienced, and he stated "that was not fun at all". I know the road well (local) and skipped over the yellow line twice, and got really close to the white line once. I thought I lost the FZ1 rider twice, but he was being more careful than I, and showed up in the mirrors eventually.
Luckily there are many more roads around that I will frequent now. I have to recommend scratching this one off your BRP run.
Anyone that rides 63 out of Hot Springs, "Shiners Run", I noticed the same last month.
