Correction: one does not walk a block in Texas, for there are no sidewalks. One drives a block, like god intended! That's why we were born with wheels instead of legs.

(I've only ever been to San Antonio for a work thing and I am very bitter about the fact that attempting to walk the half-block between my hotel and the nearest grocery store for some snacks was an absolutely miserable experience due to poorly maintained sidewalks that disappeared and reappeared at random. To say nothing to the fact that my hotel was less than a mile from where I needed to go, but couldn't walk to, due to the mega-highway with no pedestrian crossing between the two.)
