I am idling the winter away planning a 4 day trip for my dad and brothers this summer. Day 2 of the trip runs from Missoula MT to Jackson WY through Yellowstone and the Teton National Forest. The mileage is definitely ok (shortest day of the trip) at 434 miles. What I am worried about is time. Ride Planner has it at 8 hours of saddle time. My experience going through Yellowstone though is that it is pretty slow going. Any thoughts about that day? Not sure what I will do to change things up but... looking to plausibility check myself.
