My advice is to read as much as you can on this site and others like it. Sign up for hunts like the ones Cresson Sportsmans and Mosquito Creek have, and talk to/meet as many people as possible. Pick their brains. Get out into the woods. Trial by fire seems to be the best way to go, but the other stuff will help lessen the learning curve. Also, don't forget that when you've become a much wiser, and more effective caller/hunter, to pay it forward.
I'm still learning myself and just joined the board, but have been killing foxes with a call since I started hunting in 1988 when I was 12. The guys here definitely know whats up and I've learned a lot already. Welcome.
