This one came up in conversation at the lunch table today, I almost forgot about this one..

Last winter we were working with a local construction company at the mental hospital here in the city, replacing the concrete bases of light standards in the parking lots and driveways throughout the complex.
The last one of that day, we pulled the pole off, set it off to the side and the construction company barricaded around the concrete base, which I might add only stuck out of the ground about 6-8 inches and had 4- 3/4" bolts sticking up.
Now we did get some snow that night and the lot was plowed and somehow the barricades must have got plowed in and over, and the base got covered with snow.. Also in the middle of the night someone came joyriding (tresspassing really) through the lot and must have thought they were going through the " small snow pile". WRONG.. The next day all we saw was tire tracks leading up to what was the snow pile, a now uncovered concrete base with all 4 - 3/4" bolts bent right over, and pointing in the direction of travel of whatever hit it, and a LOT of transmission fluid in the snow..
Also noticed where the "mystery vehicle" came to a stop ( after it went right over the base!), a set of "dually" tire tracks like that of a tow truck were also present. The baracades, GONE, dont know where they are to this day, and we never heard a word about anyone crashing into anything by the hospital, staff, passers by or the guilty party!
