August 10th

We returned our rental car first thing in the morning and picked up the Triumph which now had air in all tires, including the spare.  After a quick breakfast we headed north by northwest toward Yellowstone by way of Casper, WY.  This was going to be one of the most difficult legs of our trip.  It meant through the Rockies fighting high temperatures and high altitude.  We made it through the mountains ok, stopping every couple of hours to allow the engine to cool down.  I adjusted the idle to keep from stalling.  The carbs were starving for air.  The trek from Casper to Yellowstone by way of route 20 was absolutely breath-taking with many stops along the way for photos and again talking with locals and bikers.  We made it as far as Thermopolis which still left us well over one hundred miles from the entrance to Yellowstone.  We stayed for the night in Thermopolis, home of the world's largest mineral hot springs.  We took full advantage of the hot springs, soaking in the hot mineral baths .... it was soothing and put us in the right frame of mind to continue our journey the next day.
