Is there anything against renting an ECV as a young able bodied individual? Afterall it seems many in the park do not use mobility equipment off site and why walk and stand on my feet when I can sit and ride? I think using an ECV or powerchair (with joystick) would conserve my energy and be a fun way to get around the park. I used a powerchair for several after a skiing accident and it was a great way to get around my campus and city using public transportation.
