Ill second the OnX Hunt app and map chip if you have GPS unit. Lines get blurry in areas you may not have hunted or when you crested 3 false summits and finally find that valley! Also have put some land owners in their place with the apps and GPS showing I hadn't drifted.If you decide on one or several GMU's, make sure to look at OnX or another app which shows private land boundaries. Some OTC and even lottery units are peppered with private land. The animals seem to be property surveyors in the off season, since they know where to go.
