Since there are about three grocery stores within a four mile radius of my home, I rarely ever have to take my car. With the exception of unusually heavy and/or bulky items, almost anything I need can be stuffed into my rack-trunk, backpack, or panniers; and I even manage to get a little workout in the process (turrain is moderately hilly). All without polluting the air, consuming a diminishing natural resource, or adding to the already supercongested roads.
As I pulled up to the store on Monday, for some pre-holiday-dinner shopping, an woman stopped me and thanked me profusely for not driving; said, "There are too many cars on the road; it's good to see someone not adding to the smog..."
I had a massive SEG on the ride home.
(SEG = S**t Eating Grin for all you sick wankers out there).
