Do the math, get a faring, save the world
Roof racks rob you of gas milage, most folks who love the outdoors are also concerned with the overall state the of the world. Here is some simple math. My faring increase my gas milage by 1 mpg (from 19 t 20), at $60.00 and $3.00 gas the faring pays for it self after 7220 miles. Americans average about 15,000 miles per year, so the faring pays for it self after six months. Of course this is very simple math, it ignores several variables which are beyond my calculation here, but I think the general concept is sound.
