I understand the allure of the Dragon, especially if you've never done it and are in to trophy T-shirts or stickers, but most locals will steer you to better rides, perhaps with less well-known bragging rights. The last time I was there (and probably final time) was a weekday and I only saw one other rider on the route (weird) that I caught up with at the end. What I did see soon enough, through the trees on a bend ahead, was a black and white cruising the route obviously looking for someone getting frisky- and on a low turnout day like that. I forget the speed limit now (it's been lowered), but it's way too slow for us straight and narrow law abiding citizens.
My point is that unless you're willing to risk a ticket in the most likely place to get one, the road is reduced to a bit of a kiddy ride, in my opinion. Many times you'll end up stuck behind some popular cruiser brand rider that is gripped just to be on the ride at all.
I'm fairly local and I've done it several times, so I'm not judging, but really when the locals tell you that there are better routes out there- it's really true.
