The family road trip was in jeopardy when my car's tire pressure light went on during pouring rain. When I checked, only one tire was low and upon further examination, I could see the nail head in the tread. The 2 tire repair shops in Preston Minnesota, where I was at the time were both too busy to be bothered with fixing a tire. I drove on to Harmony, Minnesota where I was able to get it repaired at Harmony Repair Services. Even though the inside of the garage was completely filled with vehicles, the owner/mechanic had me pull up to the door and he fixed the tire in about 15 minutes.
