The bars slide back and forth in that track. There is just a spring tab to press down to get them off either end.

One person can do it, but it's difficult.
With two people, it's a piece of cake to remove.
Easy. No tools required. Takes 4 minutes with 1 person. 2 minutes with 2 people.

You can put them on at anytime.
Probably worth 0.5 MPG at highway speeds, and not much around town.


P.S. 70 MPG is not easy, nor my typical driving. Typical for me with no A/C is about 42 MPG highway, 48 MPG city now. I'll need A/C ( for ME! ) soon!

Enjoy! I think you are doing very well Shannon, and taking everyone's suggestions to heart when feasible. For the first 6 mos. I had mine, I didn't have much data nor experience, and I was getting about 32-35 MPG.
