Brushy pretty much nailed it. I remember the same thing happening up in the Mt. Gretna SGL's quite often. I would overcome the problem by going in deeper than most do getting as far off the "beaten path" so to speak as one could. I know Pa USED to have the highest sales of Bow licenses than any other state and the SGL's would be littered with Bow "hunters" freezing the deer up and turning them nocturnal fairly quickly in the SGL's. No telling how many idiots I saw coming in to set up stands after first light. I don't know what kind of weather you guys have been having but it used to be pretty dang warm during the first couple of weeks of bow season. That will make the deer sluggish as well being as they more than likely have grown out their winter coats. About the only thing you can do is try to go deeper in and try to set up closer to bedding and water holes.
