I'm looking for a heavy duty power chair or scooter. I have to pay out of pocket, but want most heavy- duty I can afford so I might be able to go birdwatching again. Medicare won't pay because I can still walk in my house. But that makes me house-bound since I don't drive. I might be able to buy second hand. Does anyone have a recommendation for a good brand of a chair or scooter that could pull a wagon behind it and be sturdy enough to take on an easy trail? I dream of getting out to activities instead of being trapped here at home. Taxis are expensive and don't solve the birdwatching/trail problem.
