70 acres is a nice sized property but really, a 1/2 mile is not that far to go. I understand nasty cover, briars, hawthorne, multiflora rose, and everything else that wants to poke you as you walk through it, beleive me. I also understand steep ravines. Much of the land in NH and Ohio I've hunted is like that. It may seem like a hassle, but could be well worth it. I would not hesitate to carry a ladder stand 1/2 mile if the spot was good.

Making a trail to get you in there is a good idea, but consider the wind when you lay it out if possible. You don't want the deer to wind you before you get there. Maybe two trails are needed, depending upon the wind? I'm talking narrow trails, wide enough so you can walk them, not atv trails.

Getting deer out of these areas alone can be a chore, but with a cart it can be done. It's not a race, take your time and get it done. In KY (Daniel Boone NF Primitive Weapons Area) I shot deer in locations where they had to be pulled up really steep hills. With a buddy, it was pretty easy to run 100' of rope up the hill and around a 4" sapling with smooth bark. With the rope tied around my waist and the other end tied to the deer, I basically ran down the hill, and my buddy pulled the deer up the hill.

It is work, but when you think about it, it's a good problem to have.
