I've got a coupla nice bucks withing sight of main highways on public land. Again, the secret is not how far you go in, but finding a spot where deer want to go and are not bothered by other hunters. Sometimes these places are not obvious, because the deer only go there when they are heavily pressured, thus preseason scouting shows little or no sign. Later part of the season or right after the season ends there will be fresh sign. I like snow and the last part of the season. Find an area where there are few human tracks, and you will generally find the most deer tracks. Sometimes you need to put the location down in your journal for next year. Sometimes, the next year the deer aren't there because someone else found the spot or pressure has changed. The better you get to know the area, the more of these little out of the way spots you'll find. Blood trailing archery shot deer showed me many of these. After a few years and several bucks heading for the same dense area in a secluded swamp to die, tells me it's not a coincidence. Once you find a spot like that, you know most other areas similar may hold deer.
A few years back I had parked my truck at a parking area in a large state forest area. We has just received about 8 inches of snow the night before. I was walking down a U.S. highway to get to an area I regularly still hunt late in the season, an area I know for years got little pressure from other hunters. As I'm walking down the highway and scanning the woods on either side of the road and for tracks crossing the road, I notice something brown amongst all the pure white on a small piece of high ground in the middle of a swamp, not 100 yards from the road. I know odds are it's a deer and I'm being watched by it. Stopping and getting out my binos would probably make it get up and go. So I continue down the road, downwind until I get out of sight and begin to work my way back as slow and as quietly as possible. I also have to make sure I'm a legal shooting distance from the road. The heavy snow cover hanging in the thick brush did a good job of concealing me until I got to the edge of the swamp, with the small island less than 100 yards away. Putting my binos on the spot and watching for a few minutes, I discovered there were 3 does and a nice basket 8 bedded there. I had tags for both. All I could see from the woodline was their heads. I didn't dare try to re-position myself because they had already spotted movement from me that made them suspicious. So I wait, swapping my binos for my gun. Finally one of the does stood up, and shook herself off. Then one by one they all did, with the buck being the last. Having my scope on them for the last hour, I was ready and took a good shot, the buck took off and dropped after about 40 yards with the does all looking at him. I swung back and took one of the does. Usually the drag outta that area is long and hard, with one deer, by yourself. Today, I had two deer less than 150 yards from the road and fresh snow to drag them thru. Sometimes, you just get lucky.
Still, the water in the swamp between them and me, was thigh deep........
