Being Alaska and a woman who treks out in the wilderness alone you never know what you can run into. The only time I had to use pepper spray was on a red fox. The fox like this skinny wolf started to follow me and would not leave me alone despite my attempts to chase it away. I pepper sprayed it and it fell back behind me and gave me the evil fox eye with the one the eye it had managed to barely open.  The fox came at me for one more round and it got the same, a short effective burst of pepper spray.  I found out later that the guests at the lodge on Lake Louise had been feeding the fox. In September when I was home after the fox incident I looked on ADN where people post the photos of the Alaskan wildlife they have seen, the first photo was the red fox from Lake Louise.  LOL
