V,

Honestly, there wasn't that much traffic, and it's just as twisty and turny for the cars - they're going slow too. Really, there's usually plenty of shoulder, or at least, a stretch of dirt before the edge. Checkout the Ride the Rockies page on Facebook for lots of photos of the ride out of Ouray. Supposedly, a local brewer painter the Bike Lane on that section - most of the road is great, just watch for crosswinds - that was pretty harrowing for me.

How was the North Rim? We had to cancel that part of our trip. Next year, for sure.
