Most of those caches are in what is known as multiple use areas. Geocachers need to be mindful of others just as the others need to be mindful of others.
I find the remarks made by the "Guide" to be a bit disturbing. He was not being forthright or honest with you. Most guides I have met or know are very mindful of others who are in the area. If he has his clients that close to the road he should consider moving them back just a bit. Most bear baiting stations I have seen (and I have seen a bunch of them over the years) are well back from any of the "Main Road" areas. They are usually in "dead end" areas as well as places that most regular vehicles would have a tough time getting to.
Being a hunter I have had many meetings with folks that I did not expect to be there, but I always felt they were as justified as I as they did their thing.
I'd really rather not cache, but I am helpless in the grip of my compulsion!
