Nice bucks on the wall! as far as seeing the same deer year to year. Deer follow patterns. Scrape lines, rub lines etc. Set a camera up on a scrapeline. when you get a buck on it, cover that scrape up(with leaves etc.) and more likely than not, that same buck (among others)will be back to check it. Deer are also territorial, to an extent. Except during the rut where bucks will travel literally MILES, they generally stay within a certain square mileage. Of course like I said that is assuming that other people pass on them/ practice QDM. Around us, the 130's walk, and it is a generally excercised practice around the county...so the likelihood of seeing the deer the following year is better than you'd think. It's especially neat to find sheds, and then see the deer of those sheds the following season. I realize this certainly isnt everywhere but..around us thats not uncommon
