Walkable to me is not desireable. I want to have a couple acres and drive my gas guzzling SUV to work everyday, by myself.
I have friends in DC and Manhatten have spent weeks visiting both. I could not live that way. Like too many rats in a cage, all those people in one place, kinda freaks me out. Fun to go visit, but to live, no thanks.
Currently I carpool and rent an attached home in Carlsbad. Very nice, plus I can wave to my neighbors from all the windows. They are very friendly and often wave back. They even call my landlord to let her know my dog barked.
