On our return trip back home from S.C., once we were heading back south on I-95, we saw many exit ramps blocked. A few smaller towns had law enforcement cars with their lights flashing, parked sideways and blocking the off ramps; other exits along the way had military personnel and vehicles blocking off the ramps and we even saw a few off ramps with heavy equipment like earth moving machines, blocking the exits from the interstate ... and then we began seeing large signs posted at some exits saying "NO GAS".
