Thanks guys.. This is the stuff you learn from experience, and I have next to none of that..
I take scent seriously, I go through quite a ritual before heading out, right down to the scent of my foot prints.
Today I noticed there are a bunch more little does than there have been in the past, in odd spots too. I always walk their paths to and from the bush, guess I shouldn't be doing that.. It has not changed their habits yet (I do this almost daily) but it may backfire on me when it really counts.
