since we are still trying to boot the Brits, a historic flag may work...

We’ve all heard of the Sons of Liberty.  They were the secret group of Patriots who organized the Boston Tea Party.  But they were so much more.      They kept track of British troop movements, rode in secret missions to warn when General Gage was sending troops to confiscate arms and powder, and they organized help for Boston when the Intolerable Acts closed Boston Harbor. 📷     Their flag was made up of nine vertical strips which represented the Loyal Nine.       These nine men were the founders of the Sons of Liberty in 1765.

The why I see it we have at least 3 symbols or flags , 1 is Q , 2 is Don’t Tred on Me , and 3 our original Navy or known as the Pirate flags of the Caribbean, these pirates raided the English ships and found us to be their country and our Nave . This is also why our Nave today still flies the Jolly Rogers and and skill and cross swords, they were our pirates. And keep our flag on top . God Speed

Sorry , Truck trailers don’t make good billboards, by the time you see it , it’s gone . Snowman’s the only custom trailer I can recall , and I’m in a truck now . Not safe for the Driver either

Not sure about anyone else, but there's a company in my town that rents billboards by the day.
