The past couple years, I hunt land that can be described as the side of a ridge; you cut across hollers perpendicular to the ridge, trying to catch bedded deer unawares. What this means is that, more often than not, when you shoot a deer you get to drag it downhill on a leafy forest floor.
When my dad and I went still hunting in South Cherokee National Forest in Tennessee, it occurred to us that hunting in hollers isn't always that convenient. Just to get in to the area you want to hunt, you have to climb over terrain you couldn't imagine dragging a deer through. We ended up not seeing anything but beautiful country (which always makes it worth it)---we were basically in black bear habitat during hibernation season; little to no sign of deer traffic, anywhere.

After that hunt, I don't think I'll be going back to the National Forest without a frame pack.
