With or without dogs? Without, you could walk creeks with a headlamp and look for eyes, not as hard as you think. With dogs I free cast them or turn them loose and walk with them down the creeks. My dog likes to go out and then comes back and checks in every 15 or 20 minutes, unless he hits a track. LOTS of fun!! I use a .22 pistol, but a .22 rifle works just fine.
