A Montana man mauled by a grizzly bear, twice, took to Facebook before he even received medical treatment to share a warning with fellow residents and visitors to the area; carry bear spray and “be safe out there.”Todd Orr, 50, of Bozeman, knew he was lucky to be alive. He set out for an early morning hike in familiar terrain on Saturday and dutifully shouted out every so often to give any lurking bears a chance to clear off, but it didn’t work.
