I know what I'm doing if I live long enough to become too old and feeble to drive.
I'm hiring a highschool kid or two to haul me around in a sidecar rig in the afternoons, if I have to do any errands. I'll bet I could pay them peanuts, and still go wherever I want. Then I also still get the excitement of being out on the road.
'8yrs in the Marines, 'almost a decade of knocking heads in the service industry, I took a ride out to visit family and friends for Thanksgiving at 41yrs old, and my mom confiscated my bike.
