Man, that is horrible, sorry to hear something like that, especially when its out of your control. I guess I have to count myself lucky. We hunt the Peoria/Fulton County area and it has been one of the better years we have had in a while. I've seen more deer than I have in a while. I was also in southern Illinois to for first gun season and had really good luck as well. From what I've heard, it can be devistating in one spot, then 5 miles away no effect. If were lucky we won't have anything od this caliber again for a while!.
Hopefully your herd recovers fast!
