I haven't yet but I spent most of the last three nights doing research. I plan to hike into a wilderness area in the Florida panhandle and hunt deer in the January "cold" to learn about how it works. By then I will have filled mine and all my "dependents" freezers with a south Georgia deer limit ( 12 ) so I will not feel any pressure to shoot deer , just relax and learn. The goal being a solo elk hunt in a wilderness area in '13.
