I rolled through there on Friday the 13th. There was a big crowd at Deals Gap and a couple of troopers poking around. Next ones I saw were about 5 miles in looked to be 5 or 6 of them with a bunch of riders pulled over. Saw a couple more headed that way soon after. Didn't really have time to do much more than glance at them.
Biggest issue that day was meeting a semi coming the other way. He was using both lanes and some of the shoulder, a real ass. I had to pull off in the dirt and let him pass.
We came in from the east on 28 and traffic was almost nonexistent. And except for the semi, 129 was had only light traffic. I caught one pickup who was poking along, but he pulled off and let me bye without too much delay. All in all, I liked the ride on 28 better than 129. 129 is not all that difficult, it just takes a higher level of attention and endurance. It's not at all like the roads we have in this area. Here the hairpins tend to be at the end of long straightaways, so speed and braking are more of an issue.
On 28 we did see some people loading what was left of a sport bike onto a trailer a few miles east of Deals Gap. I guess someone has to feed the tree. Better them than me.
