Allison,

Welcome to the forum. I really enjoyed you blog and I thought you brought up some great points. I didn't really expect "A Complete Guide for Solo Hikers." But Googling other sites, yours is very good in comparison.

Personally, I don't consider backpacking danger to be a function of being solo or with someone. I feel it's more a function of staying well within my personal limits and keeping a large margin of safety. This can apply at any skill level and whether solo or with someone.
