How big a flag you flyin ??????
If it's not tooooo big, you might find a old Fishing Rod and mount it to the carrier with some clamps or whatever.....
Big Salmon or Surf rods are pretty stout and should hold a flag so long as it's not too big.
Check re-sale stores, pawn shops and garage sales.....Remove the guides...
Or buy a new Blank if yer bucks up......"BH"
