I have come to backpacking rather recently, and enjoy it immensely. I do find myself concerned about my personal safety on the trail- particularly because when I backpack, it is with another middle aged woman like myself. We've had a couple of situations that were not comfortable (camping within a few hundred yards of an ATV trail and hearing them 'play' into the wee hours of the morning; meeting other hikers who literally made the hair on my arms stand on end with uneasiness) and made me aware of my vulnerability. I do such things as being vague when other hikers ask us questions about our itinerary, and making sure all of our equipment blends in to the environment (no blaze orange tarp). We always leave an itinerary with family. We do not camp within sight of the tail. We probably also do other things which escape me at the moment.
The main thing is I want to enjoy backpacking without fear. I want to make sure I'm doing everything sensible to keep myself safe and then relax and enjoy myself. The problem is--what is everything sensible?
