Here is a
Nov 10th press release
...""Local distribution and abundance of fall foods, weather conditions, hunter distribution and pressure, and other factors can have enormous impacts on what individual hunters will see. And don't forget that after tough winters - like Pennsylvania's last two - deer can become more concentrated in areas where they were forced to move into to survive winter, and less likely to return to the areas they left."
It looks like the PGC is already placing blame on weather, fall foods, and pressure but the rifle season hasn't even started.
