When I was younger, I drove my 64 Sport fury cross country three times. Now the speed limit back then was 55 MPH, so my car got 20 MPG on the hwy. AND it was a B body car. And I was a lot younger. It had no Ac in it as well. I can see that once I drive the dart there, looking to get it trailered back!!! Leave it at Rays, fly back, till next year , and bring my Truck and trailer!!! that would be bad....
