You don't know much about the way a lot of independent truckers do business do you? Some of them are ornery, independent minded mavericks who don't always go by the same rules the rest of us do. Quite a few deal mostly in cash, sometimes large amounts of cash.
I know because I used to buy and sell used cars, trucks, and RVs for a living way back in the early 1980s after Carter's economy put me out of my previous business, and I dealt with truckers quite often. Once a scruffy looking old guy who smelled like a wet dog brought a paper bag of bills into my office and counted out $24,000 in 100 dollar bills to pay for a vehicle. That may not be the smartest thing to do if you travel around the country a lot, but he wasn't breaking any law by doing it.
I would like to know since when it became illegal to deal in cash?
My grandparents didn't trust banks and pretty much lived their entire lives dealing in cash and money orders.
This is all about government controlling our lives and limiting our freedom.
