I am in a middle economic strata and my friends ask me why i bike instead of driving. I tell them so i don't turn into a total fatbutt like them
and cause I like it.
Convince them it's fun. they'll come around, or at least start thinking about it.
In the last couple years, as gas prices have risen, I am seeing 4-5 times as many bikers in this college town. That means 2 bikers per day instead of 2 per week.... but still, it's gathering momentum.
Cheers
