@Moose72:

I'm sorry to hear you are not enjoying your adventure as much as you'd hoped. I'm 55 and i had a similar experience last year when in a wild and impractical mood i decided to attend a fun craft-making special event in the city in an area not known to me. Well, it turned out to be a real fiasco getting there and back, i think it was eight buses all told and i was so stressed-out and exhausted and disoriented i threw the craft away.

Like you, i enjoyed adventures when i was young. But like you my lower back and feet were so sore and i was so full of anxiety and disoriented that it was just a bad memory. I've accepted that the time in my life for adventures has passed and that quiet calm days at home are what i enjoy now. I rarely go out of the neighborhood. I'm fat and out-of-shape. The wheelchair sounds like a good way of making the best of the rest of your activity.
