Awesome idea! I like hunting this way. I'm not a believer in GPS though. When "going in deep", you want to travel light. Good, reasonably light boots, polyproplyene unerwear and wool outerwear. A light, scoped bolt action carbine, tag, knife, rope, sandwich and a liter of water. Also map, compass, waterproof supply of matches, flashlight. You have enough crap to carry as it is.

I use topozone, because I have access to good color lazer printers. Otherwise obtain a USGS 7.5 minute quad map. Google topozone or USGS. These resources will show you plenty of country.The 7.5 minute quad maps are amazingly accurate as far as terrain goes, and even if they're 30 years old, the terrain really doesn't change. Another important consideration is scale. If you learn how to use these maps, you can determine how far apart certain terrain features are, how far from roads, etc. Look on the map for saddles, swamp edges, creeks, "swamp islands", common sense type of terrain features. Spenda lot of time hiking and exploring with map in hand. This type of hunting takes a lot of scouting time. Best time to scout is during open season or right after. Spring is good too. Plan your hunts with wind direction being a primary consideration. Travel into the wind, and set up your blinds to take advantage of certain wind directions. Seek out some decent buck sign. It's only common sense. If you're going in that far, you want to have a good reason.

I've run into ground blinds also in some very remote locations, and some very good locations, you just have to tip your hat to the person that made them. I don't consider it reason to not hunt an area however. Check the location after season to see if the blind has been used.

Plan ahead for dragging considerations. Inform your hunting partners, or someone, of what you are doing and what you will do if you score. Personally, I would never leave a deer out overnight, unless I absolutely had to, ie: life or death situation.

Keep in shape. This is not the type of hunting for a fat old man who smokes. Good Luck
