Texas found their propane Tankers

I got the news that the tankers were found and they were full.  The idea of two trucks missing  then being found is most bizarre.  I wonder if the terrorists did take them then got nervous enough to abandon them.   I'd check the composition of the propane and... I'd look for devices of a suspicious nature.   Perhaps the trucks can be set off via remote by a phone call.    At any rate, I'm glad they were found.  I still don't trust the whole ordeal.
