Kim,
I don't know how old you are, but since you know about estrogen I will assume that you are old enough. I pee in any scrape I come to and make mock scrapes with my own pee. I am looking for women that deer hunt to make scrapes or freshen up existing scrapes with their urine. Preferably women that are not on birth control. I want them to especially use urine from the ovulation time of their cycle. This is to see how bucks react to it. If it works, think of how easy & inexpensive this scent would be to get. I have pictures taken of a 140 class buck the very night I peed in the scrape. If you chose to try this study, keep me posted on the results. I am having trouble finding volunteers. If you don't want to go in the woods, pee in a bottle & take it with you. Urine is urine.
