Off Road Park Flag Mounts

[Outdoors]

So I am going off roading with a guy from the Hummer off road engineer team. Plus another GM engineer at a place called Holly Oaks.

Any suggestions for a front mount? The Hummers have pole mounts made for them. They are MFG however, and added.

Edit add: Is rear bumper magnetic? Edit: Nope
