I was told that if I slept near a shelter that I would be more vulnerable to bears as they "know to come there for food" rather than sleeping away from shelters, is this true? Also, if a bear is sniffing around your tent at night, do you just stay quiet and pray or do you attempt to scare it off by making some noise or shining a light? Thank you. Sorry for the seemingly stupid questions, this will be my first section hike and I would like to make it back to my children alive!
