How many times have you watched a Vid or Demo, and as he finishes the set the person looks at the camera, or group, and grins that the set will "catch the next ( whatever) that comes by"?
He's right, but how long till the next critter COMES by?
Every area has terrain features of some form, that act as funnels or fences.
Think about your own house. You have a bedroom, kitchen, bathroom, living room, attic, and basement. And a front and back yard.
Let's say I want to set a trap for you, where would you be most likely to walk. The attic? Yes you go there and a set will get you but it may be months before you go up there.
Same goes for the basement. Front yard, back yard, weather will effect that activity.
It's more than likely that you will go between the food and the bedroom most often. With a side trip to the bathroom and the TV in the living room from time to time.
All I have to do is look for a spot where the paths between those areas cross.
Same goes for any critter. Find the food source, look for a water source, then look for a safe place to lay up. The trails between and around will be worth checking. Anything that effects travel between the areas like fences, swales, ditches and such will narrow the search.
