There's a movement to begin fueling semi's with NG, that should be interesting, hard to turn off when that's what's running your engine. As for this I95 tunnel business, is it no propane or just be sure your propane's turned off?

I think that NG is not quite as bad a propane. Propane is heavier than air so it will accumulate at the bottom of a tunnel where natural gas is lighter than air so it should disperse.
I would have guess that tunnels would have venting to prevent any kind of gas accumulation though....
