This took place in 1999, shortly after I bought my Jeep Wrangler.
For a couple of weeks, I parked my Jeep with it's rear wheels on the ground, and the front wheels on a snow pile.
Then, one day after work, there was a note on my winshield. I expected a "please don't park here" message.. but instead it said...
"A real Jeeper would have put it on top"
So, I did.
These pictures were taken after this story takes place, and I got a $15 parking ticket for "Other violation". (The snow in these pictures was plowed from the parking lots, after they put large ammounts of salt/sand down. That is why it looks like dirt.)
They were concerned that the snow may melt and my vehicle would shift in an unsafe manner.
