Why bother with National Parks?

I have used a mobility scooter in many parks. Sure it can be tough if there isn't a sidewalk but I can do boardwalks until I come to a stair. Lots of people might be able to help you get it up a stair. With your limited ability to stand and walk, 2 mobility scooters might just work fine. Some tour buses even let you store your scooter in their place while you take a bus tour. Figure out where you want to go and then look at the availability of handicapped options... From campsites to special tags to take a vehicle into places only the buses go. If I am having a bad day, I just go to an overlook and sit. Spring and Fall are great travel seasons. If you have handicapped vehicle plates and need to rent a car, look into getting a handicapped hang tag. I have e-mailed parks about certain things I want to do and ask how I could do it - most of the time, I get a great answer back. If things don't work out, something else usually does - like the time I couldn't go any further on the boardwalk at Yellowstone (stairs) - turned around, and had a bison cross in front of me! Hubby never saw it since he took the stairs! We do boat trips and bus or trolley tours if available at the parks.
