I call mainly farm land. So I park on tractor path and walk to location. Try to keep pickup in low spot or behind brush. Sometimes walk 100 yards.
I do plan to leap frog from spot to spot in a circle or cloverleaf pattern to and from home.
Most of my locations are scouted or been calling there for years, so I know the area and know where to set up.
Years back, I have tried road call'n with so-so success. From my observations, when stopping on the road to call, you may not have good location or setup or crossing, plus you may not have a clue of the population density if you haven't scouted.
By scouting an area (pre-season and in-season) one can get a handle on 'what's happening now'. When scouting, one can also chose setup locations to take advantage of Canine or Coon approach. So scouting you are not only looking for droppings and track, you are then looking for an ideal setup. And once you find that this is the place and found a good setup, you can trim some limbs, move a rock or two and clear some leaves.
When corn is taken off in my area, predators change their home range and pattern. As well as during Deer season and after Deer season during snow cover and extreme cold and freeze up. So in-season scouting will aid in your success. Know where they are. It's not how you call, it's where you call.
