Free: Contests & Raffles.
I went out this weekend to a walk in area. We arrived Friday afternoon and went out for a glassing session on the ridge that evening. When we came back to the trail head where camp was made there was another hunter setting up. We went right up to him and introduced ourselves and our intentions for the morning/day and he shared his. Turned out he was archery deer hunting while we were bear hunting. He was cutting out in a completely different direction then we in the AM so no conflict of interest. We had a nice chat and shared any information on each other's respective target species for the area. I know this may not always be the case in chasing different animals but I would say communication and respectfulness is paramount. As a new hunter though the showing up to a large swathe of public land behind a gate to find others there is something I'm not entirely sure how to navigate. Is there a general "acre to person" ratio one could use? In general any gate I've come across over the last two seasons with a truck in front of it I just move on.
I'd move on to another spot
Depending on the size of the swath of land, I would welcome another hunter or two in the area I was hunting. If another hunter bumps deer or elk, there is a greater chance the animals will work their way towards me. Now, if there is a small bowl or a small clearcut, I would say the rule is one party for those areas. No reason for everyone to have a crappy hunt. Communication will always be key, but as others have said on this string, be polite and creative. One of my closest hunting buddies today is a guy I met at a trailhead with the same cow permit as me. We ended up harvesting both of our elk at the exact same time during that hunt and have been close ever since.
