I can't really speak to your hunting situation because I'm out west in the Rocky Mountains. For me it's elk and mule deer, and I hunt on the ground, mostly spot and stalk. And I hunt public land, mostly national forest.
I've found that hunting a different area keeps things fresh, and interesting. Granted, you have to hunt an area that holds game, so doing some homework and pre-season scouting is a must, but that's part of what keeps it engaging.
This year I hunted an area I haven't been to in 20 years, and a place in that area that I've never been to. I didn't harvest an elk, but what I found will keep me going back for years. Chock full of fresh sign in this secluded little hanging basin miles from the nearest road or hiking trail. Stunningly beautiful. That's what keeps me motivated.
