I feel so good about myself today. I rode my bike to the grocery store. I brought some grocery bags from other grocery experiences and my big courier bag. I put the cold, sweaty stuff in the previously used grocery bags before loading them in the courier bag. I bungeed the laundry detergent to the rack on the back. And I rode home. No gas, exhaust or other unfriendly by-products of automobile usage. No extra plastic bags, etc. And the products I purchased had as little packaging as is available.
Yup, I feel pretty good about myself.
