I am going to have to use an ECV due to many serious health issues I have. I am renting one from Walker mobility. My concern is if I go into a dinner reservation, a ride, store,whatever, and I have to leave it (or can I ride it into places like "Its a Bug Life". "Great Movie Ride" etc., where do I leave those,do I just ride it in or what? If I have to leave it outside, will it be safe? I am just really concerned that while I am in a show or something, when I come out, it may be gone!
