Yes there are "slobs" out there that use any and all of the things in the article, but, as was stated in someones post, those people are poachers and there should be a very real distinction made between us and them.
The only things that I use from the article would be warm camo W/O scent lock, elk bugle/ cow call, and elk urine. NO 4-wheelers, tree stands, decoys, etc...
