Me and my brother will be hiking the AT in SNP in the end of March. From what I have read on various shelter threads bears and wildlife are almost guaranteed to be encountered. My question is are there any areas that we should completely avoid staying overnight and are there any special precautions we should take hiking through the park? What kind of activity will the wildlife have this time of year? We will be using a bearvault 450 and always store all food and anything with scent in them(toothpaste, wet wipes, hand sanitizer, etc.) and keeping them it at least 100 yards from camp at all times. I have never hiked with bear spray and not sure if it is needed but wasnt sure of what the norm was for the area and time of year. Any tips or suggestions would be greatly appreciated. Thank you all for your time.
