NOPE, don't believe in stopping them or even attempting to. I'll take a shot a a casually walking deer any day to putting one on alert that I'm around. BUT, if you usually just wait they'll stop to feed, sniff or scratch something.I've never attempted to stop a deer.... EVER.

PLUS, I've seen too many deer turn themselves inside out on TV trying to get away when someone tried to stop them. And half the ones that do stop usually don't stop until they're behind something. Some take a step, some 3 or 4. MOST ALL of them when they do stop look straight at the source of the noise. I only grunt when chopping wood. LOL
