^ Maybe he's a little old to be called a boomer? Semantics. My grandmother just got her license renewed at 90, just had to do an eye exam. She passed, but she's always complaining about her cataracts, so I wonder how well she can really see.
My wife's granfather is 94 and lives alone in the middle of Lyon, France and he can walk out his door and go to the market, grocery store, doctor, and have just about anything he needs. I'd venture to guess that he rarely leaves his little 10-block radius world. If he lived in the burbs in the US he would not be able to live alone, plain and simple.
I disagree that only people in SF or NYC are car free and in their mid 30s. Sure there are not a lot, but they're out there, how many of us on this forum are under 30? Wasn't there a poll sometime back?
