Update 3/11
A cold front ("norther" as Texans call it) has pushed down into this area, temperatures have dropped, and the very light rain we experienced yesterday has increased considerably. So, we've decided that today will be a rest day while we try to wait out the weather. It could be that tomorrow will be worse and we'll have to stay here another day. That's because there's a possibility of freezing rain overnight and tomorrow morning, and that is definitely something which is not compatible with cycling. Our decision to push on during the good weather is paying off - - otherwise we would be waiting out this weather a day's ride west of here.
