Not sure whether to post this here or in hiker safety. But I've never encountered a bear before (this will only be my 3rd section hike)...I'm doing part of the GSMNP....so my question is, what do I do if I see a bear? I've done some research, but any advice/tips? Both close up, and also not just if they are close...but what if for example I saw one 50 yds or so away...do I make noise to make it go away? Or just wait until it leaves before attempting to hike by? Also thoughts on bear bells...do they work?
