It depends on the age of the trees. If its a plantation and the trees are too small to climb, I like to still hunt them. They bed in them and on windy drizzly days you can walk thru them and actually walk up on a group of deer bedded together. I carry a shotgun with buckshot when I try this.
I don't think you are on the same page as to THICK pines. We have 400 acres worth that are so thick you can't walk thru them at all, I've tried. It's bad enough that I shot a doe with a bow this year and she went 40 yards, it took me 20 minutes to get in there and over an hour to get her out.
Our were planted in 06 and haven't been thinned or burned yet
