A couple years back someone gave me a deer cart. What a difference. It does not work well in the woods, but once you get the deer to a logging road or power line, it is really gravy. I think that may have added a couple years to my hunting. I try to hunt uphill from my cart when I can. Some advice: If you buy a cart, and have the money, try to find one with canted wheels. I have seen someone use one in the woods over rocks and logs and it worked well.
