Wow, great thread !! Lots of good advice.
One half of ManD is male, the other, happily, not. Being the male half, I will say this...
It's a dangerouse wolrd out there, and you cannot pick the time or the place when that danger might cross your path. Be it a 4 legged predator or 2, in the woods or in the dark shadows of a parking lot where some cache is hidden.
I've seen a lot of discussion about the 2 legged variety, and none about the 4. Here in AZ we have large cats and some bears. In Phx we have all manner of 2 legged creeps, as in most urban areas.
When caching at night, I carry a cell phone, my trusty Glock and a flashlight with fresh batteries.
I have heard a lot here about SA (Situation Awareness). It is of course primary. If things get bad, with good SA, you can hopefully be able to anticipate the situation some.
Another thing I have not heard on this topic though is this... ALWAYS let someone know WHERE you are going, and WHEN you expect to return. And then let them know that you HAVE indeed returned when you do. Leave them instructions to alert the athorities that something is amiss, if you have not returned in, say, a hour ??, after your intended return. At least that way, if a tree does fall on you in the woods, someone can come and help.
There my 2 pennys worth.
