Back in ‘08 a friend of mine, who is one of those old don’t trust no bank people, was headed to an equipment auction with about a hundred grand in his truck, he passes a parked unmarked marshal, that jumps right in behind him and pulls him over. The first thing he asked was about the cash, my friend explained what was up, and then asked how he new the cash was in the car , the marshal said he has a detector in his car that will pick up the strips in the money and if you travel with so much you are supposed to call ahead and inform them.....wtf.
