Started day with great breakfast. Colorado has too many beautiful vistas. Cool in morning. All went well until town on map for gas stop no longer there!!! We were committed to travel 50 miles on reserve. I ran out of gas exactly in front of gas station. Grant only had 3 tenths of a gal. Next fuel was 1 hr away. Prior to arriving we hit heavy rain in rock canyon. 2 mudslides went across highway. 5 inches deep by 40' wide. We near crapped ourselves. I thought for sure machine might go down as I had serious wiggle going. It all ended well. Now in KOA in vernal Utah. What a day. 320 miles.
