The fact that stores of all kinds offer drive-up windows is a boon to cyclists: I can get water or snack without having to choose between dragging the bike in the store or locking it outside and hoping a thief with lock-breaking tools isn't nearby.
It seems as if there's a larger and more visible police presence in Texas towns than there was in New Mexico or Arizona towns of the same size. I'd be interested in learning whether this is a real difference or just a coincidence.
With the exception of El Paso, what has struck me most about the Texas towns has been what a high percentage of the town's commercial buildings have been abandoned, even along the town's main drag. I just don't understand: what was the trend which caused commercial flight from these small towns, to a degree I did not notice in either New Mexico or Arizona?
