I realize this is pitiful compared to the trips you guys take, but a man has to start somewhere!! I'm flying into Denver a week from Tuesday (23rd) to meet my brother for an impromptu road trip. In general, here is our thought: Wed - head west toward SLC area. Th - head north to Jackson WY (a place that I have been desperate to see for a long time). Fri - Yellowstone/SW MT. Sat - head back to Denver for Sunday 1am flight. We are snowmobilers at heart, so we're primarily scouting for a good area to return to in the winter. Other than that we're looking to see as much as we can in the little time that we have. I'd LOVE to find an off-road bike rental place for a few hours, but he would need ATVs or something else as he generally does not ride 2 wheels. Anything like that in existence? Any things in these general areas that we should make sure we check out? We're open to any and all suggestions!
