Get into the thick stuff away from any footpaths and hack you a few trails in a big x shape, maybe 100yds or more in each direction. The deer will start using these paths,(it may take a while, maybe not) but people will not know they are there unless they stumble upon them. If these paths are between good food sources, then all the more better. Set you stand downwind of and overlooking the center of the x. You probably need to check into whether it is legal or not to hack the place up though since it's public land.
