Look for tracks, they are pretty good indicators of travel. U can't learn everything on the internet.

Missouri is different from PA but scout any farms with cows or other animals, creeks that cut through any fields, & check out power/pipelines. Scout these & similar places after a snowfall.
Any pinch points that you hunt for whitetails is usually a good start. Also look for the path of least resistance through or around the super thick stuff. Prevailing wind should also be considered as well But I'm not a big coyote trapper. I just don't have that big of a population
