I have backpacked, climbed and SARed(is that a verb?)with women for many years, sometimes with a romantic interest but more often not. I like good partners who can carry their share of the load, add to the group expertise, and do their best in tough spots. In my opinion, sex has nothing to do with those qualities;it is a minor criterion when choosing a team.

A lot of times, you want the ladies - when caving, and tight passages need exploration, for instance.
