For those not familiar with it, it is a 4,000 foot, 20 mile hill climb on a narrow, winding 2-lane road, little to no shoulders, and switchbacks. Peak is at 5325 ft. The road is mostly closed to traffic in the winter... so a bicycle paradise.



I consider the "Bikes may use full lane" sign as a special case that just makes sense on this road. I wouldn't put the signs up everywhere. So far I've avoided it during heavy traffic times.
