Walking cities

I've been thinking about this urban planning concept-- I love living in Old Town because I can walk everywhere, but in those rare instances where I need to drive, it's a nightmare.

Roommate went for a walk last night. He says I'm inspiring him to eat healthier-- he can't believe the fridge is so full of healthy food (I can't believe the fridge is so full of healthy food and I still can't fit into half my clothes). Anyway, he decided to go for a walk, but, in his own words, as not-a-city-person, he hesitated-- his first thought was, why not just drive?
