Here before long I'll take my 17HMR for a little walkabout around the farm scouting holes. I don't plan to kill anything on this trip, but more importantly, I am looking for freshly cleaned out holes. I start out by walking all the field edges and fence rows paying particular attention to ditches, rock and brush piles, and old buildings or foundations. I walk by all these places as well as any noticable clumps of grass or mounds in the fields. I make a mental notes of where every hole is and look at safe shooting positions to that particular hole or several holes looking for good backstops and safe directions of fire. I try to find a vantage point (usually elevated) that lets me safely shoot to half a dozen or more dens.
Then when I start hunting the hogs seriously, I pick a route that usually follows fence rows, wood lines, and ditches or hill sides that obscure my movement. I slowly walk a long wandering path along these routes taking time to glass every few steps along the way. Most of the time these walks end up being a large loop with places that I can glass from a distance, then jump off my route for a stalk. Stalks are usually slow walks using cover and terrain, then hands and knees the last bit to get in a prone position. I may walk the same loop two or three times some days and catch them out at various places along the way. When I get tired, I'll rest in the shade and take a lunch or water break and glass fields looking for more targets. I have several areas a short drive apart that I'll walk my routes in then go to the next, sometimes driving back and forth between them several times.
My vehicle is usually way away from where I'm hunting. I do sometimes take my ATV to cover useless ground between areas like wooded access roads between fields or unproductive pasture areas between good spots. It also helps to carry my second rifle and a cooler full of water and sport drinks to stay hydrated in the heat.
If someone were to follow me through the fields, they would think I walk like a blind man, turning left and right here and there for what seems like no apparent reason, but those are my routes learned over time scouting holes and shooting hogs in the same areas. It helps me remain undetected as much as the camoflauge does in my opinion.
