If you're anticipating some potential "harassment" from an Outfitter, perhaps consider having a Go Pro video camera or similar with you? If you're confronted with a situation, the fact you're documenting it on video, might keep you from saying anything regrettable, while the person harassing you may be documenting themselves either breaking hunter harassment statutes, or perhaps opening themselves up for civil suits? I know I wouldn't take any guff from someone on public lands. In Colorado, at the very least you could file a complaint with DORA, and see what happens from that?
