Well, for the most part, I keep my caching and hunting separate. Except on one notable saturday when I took my bow with me caching. Found the cache. Didn't kill any deer. But that was fine... would have been a long haul out from the cache site.
LOL!
I don't know about where you are, but here you can't hunt within 100 feet of your vehicle, so unless those boys climbed a ways from their truck, they'd be breaking the law.
Not to mention trespassing if it was private property. Unfortunately, it's the few slobs that give the rest of the consciencious hunters a bad name.
