Gas under 2 Bucks!!

Finally, they've had to pull out the "One" for their gas price sign!! Lucky me, I was running on empty....it's been a long time since we've seen gas below 2 bucks! Is demand truly lower or was it "just a speculator's bubble??"

Now I'd like someone to explain why diesel is considerably more than gasoline...since diesel is nowhere near as complicated to refine as gasoline.....
