Start with the unit, not the pin
Pick the unit from the season structure first: which tag you hold, which weapon season you'll hunt, and whether the unit's dates actually overlap your time off. A perfect-looking basin is worthless if your tag isn't valid there that week. Narrow to two or three candidate units, then open the map.
Layer public land over access
Turn on public-land ownership and parcel data together and hunt the seams: public ground you can legally reach. Checkerboard country and landlocked parcels look huntable until you check access, and some units carry motor-vehicle restrictions that change how far you can realistically get from a road. If you can't draw a legal route in, cross it off.
Read water, feed and pressure
Mark water sources, north-facing timber pockets and feed transitions, then mark every trailhead and road within two miles — pressure radiates from access points. Your final product should be three to five specific spots plus one backup per spot, each with a morning approach and an evening approach. Save them as waypoints so the plan survives contact with the field.
