Well it must of been a mirror that clipped the truck,..
And I know which place I was at today that I didn't back in,.. There was only one so I am off in the AM to return to the shop with a measuring tape, camera looking for a blue mirror with white paint on it,..
Once I find the culprit I will confront them , if they deny an act like an a$$ I take the photos and all the info to the police and file it as a hit and run,..
