Another good one I like, go at night. Use a small but powerful flashlight, like a Surefire, and a pellet gun or your .22. Creep slow, stop, shine your light in a sweeping motion all around you. Look for the reflection of their eyes. Raise your rifle and take a head shot. Your bright light will usually cause them to stop what they're doing, but don't wait too long to take the shot. It's as easy as shooting fish in a barrel.
I've had far more success hunting at night than during the day. Just make sure you know the terrain so you're able to walk/stalk with no light for a short distance. I usually walk about 10 yds in the dark, stop, shine my light and scan the area. If I don't see little eyes looking back at me I turn off the light and keep moving, slowly and quietly.
