I think this photo says it all. Next month a number of you will be climbing into treestands in hopes of arrowing a big whitetail. If you live in bear country, it's best to look up and make sure nobody is "hanging out," if you know what I mean.
I had similar advice while hunting in Texas, but instead of bears I was supposed to talk loudly before entering elevated shooting houses. It wasn't bears I was trying to warn of my approach, but illegal immigrants.
In either case, be aware as you hit the woods this fall. You're not alone out there.
