Saving Parking Spots with Furniture

You've seen it; maybe you've even done it. If you have a car and rely on street parking, spending an hour shoveling your way to said car might result in the "no one gets this spot" mentality. We get it, and always respect the claim, but we also think it's pretty weird and oddly territorial for a public space (uh, the street). Mostly, we see chairs -- sad, cold, busted up chairs -- but occasionally a table, giant box, or even a popcorn tin stakes its claim. What to make of all this? Is this a countrywide (snowy, cold places) phenomenon or ultra midwestern?

Good luck, everyone in Chicago, walking, biking, bussing, driving, and parking this snowy week!
