Good thread...I call it "sneak hunting" and have shot my best bucks, both Whitetails and Mule deer under 40ft in the standing timber. If its early season I will put several pairs of worn out wool socks on my feet (no boots I keep them in my pack) so silent sneaking.
There is always one in the pipe, safety on of course, I always hunt alone.
I learned how to sneak hunt on my own and not too many hunters do it I dont think, I hunt in the rain/snow/heat and will spend all daylight hours hunting, its getting harder to stay out all day as I age but I have more patience now.

I tape my swivels so they are silent, use no cover scent, nose into the wind, and I always hunt the same ridges as I have for 40 years now.
That I figure gives me an edge knowing where to look and the wind is generally always going the same direction so I dont waste my time. No Whitetail for me this year but tagged out on Mule deer.

I'm looking forward to some pointers in this thread for sure.
