I am doing more errands than ever on my bike, and I just LOVE it.
I'm lucky in that I live a half mile from town and from the P.O., and I live 1 1/2 miles from the supermarket, bank and drugstore. So most errands mean a 1-3 mile little bike ride. Plus the 1/4 mile steep hill at the end up to my house. On another thread I've been talking about converting my second bike into a grocery/errand bike. I just LOVE leaving the car at home. My husband does the same thing, doing most of his errands into town on his errand bike, his 10 year old Trek.
