I figure I should be getting some really funny looks next time I go on a shopping trip; I'm planning to drive the 60 miles to the city with the bike racked, park wherever I plan to buy the biggest/most stuff, then use the bike to make all the little 2-5 mile side trips that really suck up the gas. I've noticed that what I burn in 120 miles round trip on the highway is about the same amount as doing 10-15 miles around the city to different stores.
