I believe the guy manufactures and sells deer urine or is sponsored by a deer urine manufacturer.

Consider his theory against existing facts:

1. You scout your territory to determine best location(s) to setup.
2. Best territory and stand locations are determined by signs of constant deer activity.
3. In any location, there will be more does than bucks.
4. More does moving through means more sign.
5. Does leave the most obvious sign in general areas of scouting.
6. Bucks are less, bucks are secretive and elusive, and, therefore, do not leave as much sign in broad areas as does do.
7. Until bucks are in rut or pre-rut, their movements and where they move are difficult to project.
8. Bucks already know where does hang and move and will eventually begin to enter and frequent the areas
9. Best chance to kill two birds with one stone is to set up where does commonly group and move.
10. What do deer do in abundance in their central areas? They piss and crap everywhere.
11. What are the odds that a buck is going to pick out your bottled and weak estrus urine over that of a doe in estrus that just hotly urinated out of your range, or pick your laid (bottled) urine out of the numerous urine traces that are all over the area?

If you set up where does are not generally seen and normally do not frequent or move through, the odds of having good success pulling that buck off his route to ecstasy by throwing down a gallon off bottled doe urine, is very poor.
