I left my Focus in park one time and the only clue I had was the squealing of the tires on the black top as I pulled out of my Gravel Driveway. I went about 200 feet before I knew it was not the new fan belt I had put on the Cummins the day before. Being only 230 HP I am always sluggish and foot to the floor to get this rig moving with or without the Toad. Besides my road is uphill either direction from my driveway so I never noticed it. This incident only flat spotted my new tires and damaged the front wheel bearings and a couple of years later I had to replace them. Lesson learned, we BOTH check up on each other now!
