Public ground ain’t east hunting… BUT based on your post you are close to getting it done. Number one thing you need to realize is that the sign you are seeing is mostly done at night. A buck will occasionally run through there in the daylight but it will not be consistent. He will likely be scent checking scrapes during daylight down wind by a hundred yards or so. His nose is the best defense he has. He’s gonna stick tight to cover and use that nose to figure out which deer have been by that scrape. A hot doe will make her presence known by visiting that scrape line.

That said, if you’re hunting relatively close to an access point, the deer know this too. Dive in a bit further and you are likely to see more movement. If you are far off the beaten path then you need to find the terrain that will funnel deer as they travel. Bucks will make a ton of sign in a creek bottom at night but during the day, they are going to want to travel the higher ground because they can check out the activity below with their nose. Stick with it and adjust your setup slightly, you should be rewarded in doing so.
