DO NOT RIDE THIS IF IT IS COLD AND DAMP DOWN ON I-90!!
Bighorn National Forest is breath taking. Some of the nicest scenery I saw while riding out West. Altitudes will reach 10,000ft and wildlife is everywhere.
The Cody Resevoir is very intersting and the Wild Bill Cody museum is worth a visit. This tour can easily take up 2 days if you want to see the sights.
When heading back over get gas at Ten Sleep, its your last chance until Buffalo.
