Being home during the day these days I noticed that the Outdoor and Sportsman channels have paid programming. Just informercials. Does anyone really watch these things? I guess they do or they wouldn't have them, would they?
I have a sister that watches them and buys from them just like a religion. Her home is so full of junk you can't find a thing but she knows where every thing is located and and can find it fairly quickly. The funny thing is that some of these things that are sold on TV actuall work to an extent.

Another scent would almost be better named as a "coverup smell". The main goal is to cover up human odor or mask it. Though I don't believe you can ever totally eliminate all human...
