Last night my wife wasn't in the mood for cooking so we ordered out to the local Middle-Eastern restaurant in our neighborhood (about three blocks away). And, for the first time, I biked it with a backpack to carry the food.
It was dark, so I had to put on my lights and vest, but it was easier than driving. I didn't have to ride around looking for a parking space forever (though I did have to chain my bike to a street sign since the place has no bike racks), and I got a little extra exercise. I'm not sure why this never occurred to me before... but it felt good to do it.
