This is a tough time of year to be touring in Texas. I remember visiting Dinosaur Valley State Park on a May camping trip when it was 108F in the shade. When my family tours, we do much more poorly in exceptional heat. Especially when it's so hot at night. A poor night's sleep + a hot day is a sure recipe for some king of meltdown on our trips.
You have great Fall/Winter/Spring weather for touring. Perhaps you should developing your touring experience in more favorable weather?
When your having a blast on a wonderful tour in January, you can think on me riding through the ice and snow
