I'm gona start doing backcountry backpack trips in the Sierras. Iv done reading and it seems like hanging food or bear proof storage is the best way to go. I also carry an airhorn and bear maze, but I was wondering wether anyone had experience with those electric bear fences you set up around your tent. Scam or no scam?
I just want all the protection I can get and don't mind the extra weight.
Thanks in advance!
