It will be tough-impossible probably- to get older "not riders" to ride.
I guess I'm thinking ahead- with forum members in mind maybe-when you folks become older fatter gimpier-
Of course it won't happen to me-but I certainly see that in your future-
Generous soul that I am- I'm looking out for you folks!!
Yes I can see it- I-Like-To-Trike
PS Economics-depression- or a huge increase in energy prices- is about the only thing that would change our transportation habits- becoming as poor as folks in China 1980 or so.
