Cliffman,
I spent a year on scooter and crutches and remember what a blast I had going to Target for the first time on a store scooter. I hadn't been anywhere but the grocery store in months and that alone had already felt like a huge burst of independence. but adding in Target? Oh my!
You will find scooters many places for free and often for rent at museums or even amusement parks and zoos. I was able to accompany my son and husband to Six Flags on one we rented at the park and it was such a joy just watching them and being part of it all. I even went on the big rotating swings.
Don't sell yourself short. There is a lot out there you can do with accommodation. So yes I had more pain after scooting all over Six Flags, but boy was it worth it!
Keep up the good work!
