New Orleans fits this as well, as I also lived in the Tremé. I biked and walked everywhere. It was great
It's better than most, I agree, but still a far cry from NYC, Boston, or SF.
Running alongside the freeway is an access road where all the on-off ramps feed. It has a wide sidewalk along the side and it was only a couple of junctions between the hotel and the site I was visiting so I walked.
A police car immediately pulled up to ask where I was going and why? Fortunately the English accent convinced them I was obviously merely some pinko-commie weirdo and not a threat to Houston society.
Maybe it was one of the little townships that still refuses to integrate into the ever-expanding maw of Houston (think West U area)?
