On my motorcycle, I fly a 3x5 flag, mounted to an aluminum flag pole 5' which is inserted into 1" conduit mounted to the saddlebag holder with two hose clamps. I have run this at up to 70mph (not reccomended but necessary at times. I belong to a group Warriors’ Watch Riders: WE HAVE YOUR BACKS AT HOME!
that escorts returning troops, flag lines etc )
On the Suburban, I have a mount for a flag pole to be mounted into the hitch receiver. The Flagpole for this is an aluminum telescoping painting pole extension
