Yes, coming down Black Bear into Telluride CO on the way to Ophir Pass. There are two gas stations west of Telluride. One was inexplicably closed. The other was open. With the RotoPax I could have ridden the whole loop without taking on fuel. Always good to be prepared for surprises. If I hike from the bike I always turn off the gas valve. Would not want to come back and find the tank empty due to a sticking float. That has almost happened in my garage.
