RE: How long did it take you ?
I'm still learning on it. Its been 3 years now and each year I am picking areas that my buck sightings are getting better. I know the land really well but with different crops all around its taking some definite work of walking around.
And as for what has contributed to more success, I would have to say trail cams. I learned just by moving my cameras more often that you can find more of a core area instead of just a random meeting spot. Then try to breakthe core areadown a little more. Definately helped me out this year and hopefully a little better prepared for next year.
