A Message from the Founder of GreenAroundYou.orgTip: Dump the roofrack (unless you actually need it)
Suggested by Sheila Crosby.
A roofrack does horrible, horrible things to the aerodynamics of your automobile. On a long trip down the freeway, it'll cost you an extra 40% or so of fuel (depending on the make of automobile and the shape of the rack.) Takeit off as soon as you can.
