One last thing... Don't get too comfortable. LOL! A deer can materialize at any time and your shot opportunity can last a couple of seconds. If you have mini-senderos or narrow spots where you expect deer to cross, it helps to make a bleat sound with your mouth to stop them. This will buy you precious seconds to determine if you want to shoot or not. Depending on width of narrow area, a deer can cross one of these narrow spots in 6 seconds. That's not a lot of time to do much and easier yet to be looking elsewhere and miss the crossing all together.
If you can, keep the rifle in your hands at all times.
