RE: Funnels
Depending on what type of terrain you hunt google earth or local.live can be of tremendous help. If you are hunting very flat land it is a little less beneficial but in PA with all the hills, ridges, creeks etc it is unbeliveable how much google earth and locallive works for us. We use both because different areas show up better on one or the other. We always scout the area on foot for sign, then get a good aerial shot from one of the two sources above and trace all the sign on to the map. Once you done this you see good patterning of the deer on your area as well as funnels and pinch points. We take it a step farther and mark in where we see deer through the season, what time we see them and weather conditions and it becomes a great tool each year. It is way easier and inexpensive now that satellite imagery is available and easy to navigate. Good luck.
