Not a big sample but so far Nov. 9 is in the lead with 4 kills, with Nov. 12,14,15 having 3 kills a piece.
A Pa poll on another site the top days says top 2 days were Nov.9,16, Both saturdays. Top week day was Nov.4 I've seen a few of these polls over the last 4 years and my conclusion I guess is hunt as much as you can from the beginning of November on cause you just don't know when it will happen in your area. I usually take off from Nov.3-15. So far I've hit it pretty well.
