I just saw the new San Francisco Chamber of Commerce ad showing how wonderfully inviting and welcome that city is. It shows ecstatic people having fantastic fun…starting with a guy twirling around in his wheelchair. Mmmmm…steep hills, shops with steps, crowds blindly rushing about (focusing on phones, of course), uneven sidewalks, crossing spots with chewed up pavement…in a manual wheelchair with skinny tires?! I seldom try it–and only some areas–once in awhile in my heavy mobility scooter.
