Where are you located? I think people overthink scouting way too much. Tracks, trails, rubs, scrapes, beds, food and water source. For me if i can find a minimum of some of those then i know im in a decent area. Find em all and usually youve hit the jackpot. 2 deer in three years isnt bad. Heck im on a 2 year drought of zero deer right now. Not because they arent there
