I had a self-important SUV driver blast his/her horn several times, less than a mile from those Dinotte 300R pics posted earlier.
This mountain pass is the only reason I use the 300R on this day ride, and I've always gotten a wide berth from vehicles behind. True its a 45mph highway where the legality of bicycling is questionable. I hit 45mph at the end of the first tunnel, and exit the second at 50mph. Traffic patterns are such that you can time it so no vehicles catch up till at least the second tunnel.
This is almost the exact start of the descent, where you can see the end of the first tunnel. This is also where I wait on the shoulder for a break in traffic. I'm at well over 120rpm pedal speed between tunnels.

Second tunnels
