MA to GA is mostly downhill... if you play it right.
Goin down south = downhill.
That's my logic and I'm stickin to it.
Yeah, I was definitley coasting in-gear on shorter downhills, and just rolling in neutral on longer stretches. Also, it was early morning (started driving at 4 am), so I hardly used A/C at all, and was going the speed limit most of the time.
