RE: hunting on main trails on public land...
set up where u see deer. if its in a field or on a trail or w/e, if u have an idea where the deer will be then u have an advantage. in the middle of the day maybe work your way down the trail a little and figure out more of the puzzle such aswhere they bed, where the buck sign is, etc. bucks use trails whenever its safe and convenient so its fine to hunt the trails just make sure to control your scent and be quiet and use cover.
