Move these at your own risk?

[HipChick]

When snow puts parking spots at a premium, as the blizzard that just dumped 18 inches in Boston did, snatching someone’s marked space can lead to hurled insults, slashed tires or worse — in 2005, a man was arrested after smashing a car window with a plunger during an argument over a freshly shoveled spot.

For the uninitiated, a local blog, Caught in Southie, helpfully lists the “unofficial rules” for saving parking spots, including: “If you move someone’s space saver and park your car in its place, you have no right to complain about what happens to your car. However, you are allowed to retaliate as long as you don’t get caught.”
