What kind of difference in gas mileage should I expect to see once I start hittin the highway hell that is I-70 into the mountains. I'm actually putting on two racks in a "V" shape. I'm gonna put em on regardless. Just curious to see if anyone has actually measured with and without.

but the thing that drove me nuts was the wind noise. Now I do everything possibly to just use the trunk/backseat. This was without a fairing because in order to put the feet where they are supposed to, the fairing rested on the paint, and I knew from past experience that such contact was a bad thing. FWIW, this was a Yak rack.

The only thing I guess I will be concerned with are the leashes flopping around but I'll take care of that.
