If you are jumping deer out of their bed walking in, thats not where you want to be walking in at. That is a bedding area and you are screwing em up by disturbing them. Them bigguns are not gonna stay on that island. When the does start getting right, they are gonna roam around. If I were you and if at all possible, walk that power line on a day with a north or south wind and find the biggest trail crossing it to the main land. A whitetail deer is lazy. They are gonna travel the easiest route possible without being seen. Find a funnel. Once you find that trail, do not walk down the trail. Back out of there and set up close enough to the bedding area where the deer cant see you, hear you, or smell you walk in. Do not walk down the trail. Hope this helps some
