I think the better question is general walkability.

The extremes is a pretty weird trip to do comparisons of since most people go from the outskirts into the centers to work and play and then go back to the outskirts.

The question becomes... once you get to your destination, can you get anywhere else without having to hop back into the car?

In cities like NY or Boston you can ride into town, hit a restaurant, go to the show, grab a few drinks then hit the clubs all without getting back into your car or just by taking short stints on readily available public transportation or taxis.

Can you have that same experience in Houston? I don't really know. Maybe. Where I'm from it's not concentrated like that so you go to your friends house... then you get in a car and go down to the bars... then you get in the car again to go to the arena for the show.

Everything's very dispersed. I personally like that much less.
