Yellowstone is a good idea except that in the summer months they restrict the amount of vehicles they allow in the park. And I would have to check on this point but, I believe I have been told in the past that motorcylces are NOT welcome in certian areas. Maybe someone knows about this. Also, if the Montana/Canada ride becomes one of the desired destinations, one could not pass the opportunity to ride the Going to the Sun Road in Montana, or better know as Logan's Pass. This is NOT a quick ride, but I have yet to see a pass as nice as that one. It's only about 3 - 4 hours from my house and 5 to Banff. Grant Gall
