Had my first chance to do some fun driving up in the high country here in Northwest Wyoming. I was very impressed by the fact that I was able to drop down the Lovell route from Burgess junction in the Big Horn Range without touching my brakes. The grade is 10% for 14 miles of tight switchbacks. I was able to use my gear selection button with the exhaust brake to accomplish this. I was not towing at the time but was impressed none-the-less.
