For the past 3 months (since I started riding) my DH and I have been doing ALL our errands into town on bikes. Only drive when it's raining. I can't beleive how little I've been using my car the last 3 months. (we work at home)
The ride into town is only one mile to 2 miles roundtrip depending on where we are headed... but with a BIG hill coming back home.
Every time we have to go to the bank, the PO, the grocery for a couple of items, the drugstore....one of us just takes a bike now. DH has a nice basket on his hybrid, and I have a backpack I like for biking when I need to stash things. Wish we could do it all through winter coming up! But will have to quit when the roads get slushy or icey.
