Hey walle 12,
Welcome to BGH. I should also say welcome to CO. I would point you in the direction of the DOW. (dept. of wildlife for all not following at home) The website is rich in information on wildlife densities, distrubution and all the rules and regs you will need.
When it comes to scent, there are basically two types; those that attract and those that mask. I've tried both on many occasions. There are lots and lots of "doe in heat" scents, designed to attract a big buck into range. I've also used a "cow in heat" scent while elk hunting.
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...
