YOU NEVER EVER CLIMB ALONE!
The problem is when you go with someone you gotta actually interact with them on some level.
My trips are considered successful if I never see another Homo sapiens the entire time.
Seriously, I have to confess to solo hiking / camping myself and accept the consequences there of.
I also stack the deck in my favor by leaving detailed itinerary with my wife of where I will be and when I will check in and when to call the cavalry.
Haven't gotten a PLB yet, and it is on my list...
