In the morning I visited Mt Rushmore in the Black Hills NF. Crossing into Wyoming I took off on dirt roads about 100 miles long. Yay! Back to my goal. Later in Casper I headed south for more dirt roads that dropped me near Colorado. Stopped in Casper, Wyoming for fuel and ice. While I emptied the water from my cooler A guy started yelling because the water rolled his direction. Saying I was making a mess over there and I should be more considerate. Note it had been raining all day and water was standing everywhere. I said, “I apologize, but its only water.” People who herd the commotion gave the guy a funny stare.
