First, let me say that my car does not even vaguely resemble this Emoticon.
I ride a trolley to work and occasionally park at a space near the entrance to the parking lot rather than drive close to the entrance to the trolley pay booth. This makes me feel good because I am helping the environment by burning a little less fossil fuel while I am helping myself by burning a few more calories.
Recently one of my coworkers noticed where I was parked and commented that I was parking in the "Weight Watchers" section of the lot. Apparently, WW advises people to park at the outskirts of lots so that they can burn those few extra calories. I had never heard of this before. I was also not going to give WW the credit to I told my coworker that I was actually parked in the "SparkPeople tree huggers" section of the lot!
