Well I had zero luck on opening day and the second day, I didn't see a single deer or even see another hunter with a deer for that matter. The moon phase was full which did not help, the temperature was in the 50s both days and opening day rained pretty hard the entire day.
There were plenty of shots fired on opening day and a few on the second day. I know a few people saw some deer where we were hunting. Two of the guys I was hunting with were on the opposite side of the road than I was and both had a shot at a doe, but missed. Those were the only deer seen by my party. The local guys I was with were after this huge 8 pointer with Chocolate brown antlers and a 20" spread that he missed twice during the bow season. They saw him dead next to a guy from NJ's truck on opening morning after we had passed by, so someone got very lucky on opening morning.
Where I was hunting was in Pike County, near the Pocono Mountains I believe, I don't know exactly where it was since I was being driven around and not really paying attention. From what I was told, this was the worst any of the guys I've hunted with have ever seen the opening week of rifle season. I was hunting in an area with hardwoods and pines and saw numerous trails with fresh droppings and lots of rubs, but no deer. I think they just went into the thick stuff deep in the woods to get out of the rain and away from the hunters.
The two days before opening day we saw deer everywhere including a really nice 8 pointer twice, but of course these deer were not in our hunting area and on land we could not hunt. I don't think I'll be going back there next year, I just like bowhunting better, there's a lot of pressure where we went so you're really just trying to cut the deer off on their escape routes, not hunt them in their natural environment while they are not spooked.
