I have to agree with some of our commentors on the original post that the overall CO2 effect of stunts like Park(ing) Day is almost assuredly negative, but I still like the idea of transforming a dull city parking space into someone's living room or a pool (see pictures after the jump). Life is quite short, as they say, and sometimes you've gotta make your point in non-traditional ways.
