Have had happenings similar to the OP while elk hunting before too, but some times stories tend to need a lot of room to really tell the whole thing correctly. I think the OP made a great example of some types of things that can and do happen, so I won't go off again about anymore of mine. I was watching just last night where someone was turkey hunting on some private property only to have a poacher drive right through (caught on camera) and scared the gobbler away. They devoted a minute or two to talking about trespassing on private property and poaching and how it can ruin someones elses hunt and how trespassing and poaching is illegal and how it's not right to begin with. I forget the name of that hunting show.
I saw the same show last night. Guy in older truck just drove through without a care or concern. It was a father and son who were hunting turkey, but I don't remember the name of the show. Not one I normally watch....just killing time with noise in the background. They did sum up the negative impact of poaching.
Wind is one of the most crucial variables in any kind of big game hunting. It helps level the playing field between a hunter with a scoped rifle and the game animals being hunted. This is not novel information. Any hunter who has consistent success in the field knows this. I have tried a couple different techniques for keeping track of the wind. Here are a couple.
The most simple and obvious is to just stay cognizant of it. It is amazing how slight of a breeze you can sense if you just pay...
