YUCK

Amazing we still aren't safe alone, isn't it?

Wonderful advice. All of it good. Such a great forum.

The driveway one was one I used when I lived in SF. It worked.

I do carry pepper spray. It's my back up plan. I keep it where I can grab in a heart beat. Won't do you any good zipped in your pack. So keep it close and a second away from your hand, just in case. Hopefully, with all the suggestions, you'll never need it.
