RE: What really works??
Scents don't mean jack, if they're not used properly or at the right times. Early season I pretty much just use cover scents and try to stay scent free. Later on in pre-rut, and rut I do bust out the scents, but results for me are mixed to say the least.
Calls, I've also had mixed results. I use them very little, and if I have seen deer after using them, I can't tell you whether or not they were just passing through, or if they were responding to calls.
The buck/doe ratio is so outta whack where I'm at the rut isn't intense. Deer don't respond well to calls or scents.
