It might be BS, but I've heard that if a deer was alive, and jumping a low fence, and it's replaced by a high one, they sometimes jump it. While I've never seen them try, I have seen deer that have hung a foot in a high fence attempting to jump it and died. Captdavid

"It's not how hard you hit 'em, it's where you hit 'em." The 30-06 will, with the right bullet, successfully take any game animal in North America up to 300yds.

If you are a hunter, and farther than that, get closer!
