So carol, grand daughter sophi, and I are driving across state to an open house. We are passing through Flint on 69 when I spy this fifth wheel trailer just ahead of us. The spare tire is located underneath the trailer at the back, and I can see its loose. No sooner did I say..."That guys gonna loose his spare", than he hits a bump. That tire came off and bounced 10 feet in the air, hit the road in front of us and by the grace of God missed us and landed in the median. Like I said...close call. You should have seen the face of the trucker next to us. The guy didn't even know he lost it.
