Someone said on a diff link (don't want to take credit b/c it isn't my idea), but we need to find a way to run vehicles on weed. Best of both worlds! Talk about a Nobel Prize winning idea! That way we could have the exhaust come through the A/C vents and go cruising.

That reminds me of a cool saying I heard once...

"Man who run in front of car get tired, man who run behind car get exhausted."
