So was getting a few loads of firewood with some friends of mine when some kid "falls asleep", drifts over and WHAM!
I was parked with my door past the pole, so he pushed the truck back at least 8 feet till the pole stopped his momentum. Luckily none of us was near the truck when he plowed into it.... but we watched it happen.
You know Newton's Law.... a log at rest wants to stay at rest.... well a truck load of logs at rest and a truck suddenly slammed into at 30mph.... the logs pushed the back of the bed into the cab, busting the glass in the process.
Good thing I finished the demo and bought most of the materials since I won't have a hauler for a good bit
