Pretty close to 100% of my rifle hunting is still hunting the big woods of NC Pa.The first piece of advise I would give is to learn how to shoot offhand very well and practice.I firmly believe that over the past couple of decades of low pressure,at least in this part of the state,deer have evolved to lay down and let you walk past them,rather than run.Other than the obvious things like using the wind to your advantage,you want to try and start high and never move across an area that's open.Always walk in the shadows and always stop where you can shoot.Buy the best glass you can afford and use them religously.Deer will most likely.know you're there before you know they're there so being quiet isn't as important as you'd think.They just have to think that you're going to walk past without being seen.Because of that,you have to get a feel for where they bed so you can flank them,rather than walk right at them.That's probably one of the most important things.I go slow and I glass more than I walk.Most deer I either shoot them in their beds or just as they stand up.I've never had the need to shoot at a running deer.Deer usually lay in or against some sort of cover,be it a depression,next to a log or some grapevine tangles.I thoroughly dissect each piece of cover over and over before moving.
