We were Lucky

Notice the very dirty car is not on the trailer. Long story , I'll try the short version.
We had to get new tire straps so the ones Bob got went on very easily. We checked and tightened them at every stop and he had put an extra strap attaching the frame to the tow dolly. We were 3/4 of the way thru Pennsylvania and stopped to get gas. Bob made a sharp turn and one tire came almost completely off the dolly. We were so lucky he was in a parking lot and going slowly.
I drove the rest of the way and our caravan was three vehicles long.
We got here safely and are ready to relax!
