We left our park in Brady, TX, and headed west on US 87. The wind had been on our nose the day before, but was now directly on our left side. We wiggled around a bit when we passed behind a grove of trees, through a rock cut or underpass, but we ran at a bit under 60mph and thought we were handling it pretty well. Until a square-nosed truck passed us, and his bow wave unfurled the (new) awning over our slide. It's not a big awning; the slide only goes out 16 inches, but the awning unrolled completely and retracted again -- maybe two or three times from the sound of it. The mirror revealed that it had not rolled up smoothly, but was wrinkled. At our first opportunity, we pulled into a gas station and unrolled and re-rolled it.
.
Unfortunately, it appeared that it had stretched the leading edge, which can allow the awning to flop around when deployed normally over the extended slide. Poo.
Three or four miles down the road (and running only about 55 mph), it deployed again; this time with no trucks to cause it. The mirror again revealed a folded/twisted leading edge. We had only about ten miles to go to the park we had selected for the night, and so continued on.
.
Four hundred feet from the turn-off to the park, a small truck passed us honking his horn and gesturing that something was amiss. We assumed the back end of the awning (which I can't see in the mirror) was flapping, but he pulled directly in front of us and began to go onto the shoulder. Well, shoot. If he thinks it's important, we ought to humor him and pull over, too. By the time Dean got out, the fellow was running back to us, telling us that the CR-V had a flat tire. Understatement. The tire was in three pieces: The two sidewalls still attached to the rim (and holding the weight of the car) and the tread, looking like an oversized v-belt rotating with the wheel, but dragging half a foot behind the wheel well. And pretty HOT! Lots of little pieces of rubber stuck to the left side of the CR-V. The fellow said he saw us go through an intersection a mile back, and he turned around and chased us to alert us. Wow! Texas chivalry!

As we fumbled to find where the heck the jack and wheel wrench were hidden, another fellow did a U-turn and pulled in behind us and offered to help the gray-headed old guy change the tire. Which he did. For which he would take no money. Neither from the gray-headed guy nor the not-very-gray-headed lady who stood at the back of their car ready to throw herself in the path of anyone who looked like they might wander onto the shoulder and whack us. And he told us where the nearest tire place was. Wow #2! These Texans aren't a bad lot.
An hour later, we were back in our site at the park, with a new spare tire -- the guys said they really didn't have a patch big enough to fix the other one. And time to reflect that this could have been a LOT worse. We've seen tow-cars that have had tires catch on fire. Usually a blackened hulk. Sometimes ONLY the quarter of the car nearest the tire fire was destroyed -- great luck!
We'll never know if the tire was going flat for some time; whether we ran over something on the road, or whether it blew out -- we think we would have heard or felt that. Dean doesn't think he even looked at the CR-V while we were stopped to re-roll the awning -- he was engrossed in THAT problem. As it was, we never saw or felt any abnormality. People who had experienced flats on their tow-cars had told us they didn't see or feel anything. They did not lie.
We still think we're (as Gene Erwin often said), very lucky people. Maybe he now watches over us to see that we stay that way.
