> I live in a neighborhood about two blocks from a light rail stop and still walk by single family homes on relatively large plots on my walk from door to door. In nearly any direction, you are within a block or two of what one would say looks like a suburban single family home.

I live in Chicago, in a three floor walkup three blocks from an El station, and walk by dozens of single family homes on the way there. There are single-family homes everywhere, it's very difficult not to be within 100 feet of one.

Are single-family homes the enemy? I think they're nice.

edit: Houston and LA are notably strange places. I'd add Nashville into that, which turns into what seems like Russian doll-nested suburbs right after you leave downtown.

Houston is what gets held up by house-building anti-zoning advocates as a model, though, for some reason. To me, it's always been a hellhole, but I haven't visited for years.
