Anyone know how effective these refueling missions were that I heard about on the news? Some gas tankers went to gas stations along the evacuation routes, while others went to give gas directly to motorists on the highway. I never heard any else after the announcement, though.

Given the mess on the roads, I really can't imagine that either plan worked all that well.

If contra-flow had been set up and all inbound lanes were used for evacuation, how would gas tanker trucks or emergency vehicles get through to resupply gas stations along the route or to help motorists?
