30 minutes later a tire blew out. Everyone was safe, but a combination of a broken spare tire rack (making the spare inaccessible) a tow truck who of course was not at all handicap accessible (and of course the van could not be towed with me in it) and a very nice man (the tow truck driver) who gave Oscar and our destroyed tire a ride to and from the tire-store meant a very long day traveling only 30 miles from home. By the time all was settled, it was 5:30, and too late to complete the journey and have any time to speak with Dad. So we will go back in a few weeks.
It was a bit scary in the van waiting on my own. It was very close to the highway and every time a semi went by the van shook and swayed. Thank goodness I had my kindle along, and also thank goodness I still have the knack of completely losing myself in a book. It made the wait so much more pleasant. It was also perfect weather for being trapped in a van along side the freeway; mid-70s outside, 80 inside with a nice breeze coming in the window. I had plenty of water, too.
I am a bit uncomfortable from the time spend laying on the bench seat, but much better than if it had been in the car where my feet would have been down and my abdomen upright for too long.
