I should also note that I'm glad that there is a movement to make cities more walkable, but I duck out when that sentiment pours over into a sort of religious zeal against more nature-ful ways of life.
Specifically, I'd like to do more hiking and cycling, but honestly just being around it--having fresh air and room to breath is great. Also, my geriatric dog is much happier when we take trips out of the city. It's easy enough to work during the day and go for little hikes or bike rides in the evening if you don't have to drive 3 hours round trip.
