In my younger days I struggled to pay the bills. I supported a family with a pizza-delivery job. My then-wife didn't work. We did have one car, which was necessary for the pizza job. It was years before my wife bothered to get a drivers license.
I lived in a small town in Michigan, and *could* have walked or biked anywhere in town. We didn't. We drove everywhere.
It's really a matter of knowing that the option is there. I never considered it. Other than riding our bikes, how do we educate others?
I saw a craigslist posting a few weeks ago. Two bikes for sale, don't need them anymore, I have a car. Sad.
