Great stuff! You guys are really getting the full boat experience going from West to East,taking the time to do as much dirt as time permits,its a huge country with lots of variety,might as well check it out! Colorado has so much to see it could be a trip in it's self easily.
(I do feel the DR is getting a bum rap though,Ive done 650 miles a day on my DR on all hiway with stock gearing at 70/80 and even 90mph with out problems,50 mpg most all the way,fully loaded after camping at Death Valley,possibly a fuel filter is getting plugged on Shauns or something is amiss with it,shouldnt just die from bombing down the hiway,maybe dirt in the carb?) Its not like a touring bike but it gets it done.
Carry on,I'll be reading!
Some bikes around at times
