I'm a truck driver and was setting parked in a row of trucks, each parked back against the curb and nose out, when I was unceremoniously woke up out of a dead sleep by what I thought was the rocking of the truck. I'm out here about 20 miles from Pittsburgh, Pa and it's 5:30 local time. I get up thinking, "Do they have earthquakes out here?" Then I see the truck setting to the left of me had pulled out and when he turned sharply left the back end of his trail struck my driver's side mirror and smashed it.
We all got everything strieghtened out. We exchanged info and he went on his merry way, but that's one example of a way not to be woken up.
