I have a budy that has a HF place. They were watching several of the better bucks for 3 years now, how long they have owned the place. They finally decided to shoot some of them that weren't getting any better. One of the bucks they shot last year was 9.5 YO (they sent the teeth off for aging) Meaning the year they first saw him he was 6.5.
It's hell eatin em live
