Yellowstone Motorcycle Run – Day 10 Cody to Yellowstone and Grand Tetons Arrived in Cody WY on Day 8. Drizzle from Chief Joseph Scenic Byway turned to steady rain with dropping temperatures. Those conditions turned soon to mixed snow! From our hotel you could see the Cody Rodeo arena and the entrance sign to East Yellowstone. Both would be significant in a few hours. Some hours later the rodeo was canceled due to the snow / wetted conditions The sign now stated that park entrance was CLOSED. We were hopeful by morning that the weather would pass. Morning came and the weather continued. We settled in for another day / night. The next day (Day 10) the weather broke, the sign returned to OPEN and we ventured on toward to the Grand Tetons. Along the way we would see why the park was closed.
