Deer hunting, walleye fishing, trap shooting. Years ago I even bowhunted deer, and the arrows I used had the same shaft as the arrow sat antenna. Got into putting out game cameras and got hooked on building them, buying control boards and dissassembling Sony digital cameras, soldering in some wires, hook it to the board. Got a picture from one of an owl flying at night, a couple coyote, turkeys, squirrel, and a lot of whitetail deer
That game cameras thing sounds cool!
