Know your area.
Take a dog (for a walk)
Go with a friend.
Carry a small pack and a pocket guide plant book.....you just look like someone collecting for something 'arty'
Don't wear overtly *camouflage* clothing, but quiet colours allow you to blend in gently.
In a new area wear a hiking style cagoul, you're obviously just out for a walk.
Go and do a police sponsored self defence course.
Be Aware, but not jumpy.
Any of the above make things a little easier & you look as though you belong there and that makes you unremarkable.
I'm 46 & I won't bivvi out by myself even now, silly isn't it?
Most attacks on women are in their own homes, very few are by strangers, most people you meet are decent folks who would go out of their way to help rather than hurt, but we're still cautious. Men are too though, and fewer of them like to admit to feeling scared, worried, or concerned for their safety.
My biggest scare was about half a mile from my own home, re-tracing my steps up from a deep pool I found myself surrounded by a dozen adult sized teenage boys high as kites on booze and dope. I didn't confront them, just quietly 'excuse me'd' my way up to the pathway and then as the comments got really ribald slipped quietly into the woodland and onto the path home. Not funny
Met a neighbour walking his dog and walked home with them.
I just wasn't paying enough attention to who was about and what time it was.
Be well,
Toddy
