I did, and so did a couple of my friends that I hike with. It helps that our hiking group here is heavy on the ladies-so if a man joins, well, his chances are better than average.
So my point? You probably won't find love or lust in the backcountry out of strictly chance-but if you get into a group setting, your chances go up high.
Why? Well, for one thing, it allows the women to be relaxed around men. There isn't pressure to be guarded, they feel safer overall. You get time to actually know someone, and see how they react when tired, scared, stressed, etc. You have hours and hours to walk and talk.
I met my husband on a trip in the Olympic Mountains. We hiked together quite a few times in the month or so before we started dating. I didn't even see him as a guy I wanted to date until a trip in the North Cascades in late November of 2002. It was an alpine meadow, a waterfall and something clicked. That day we had hiked 12 miles together and something changed when he leaned over and helped me up the trail, covered in ice and mud. I liked the guy and I wanted to get to know him even more I knew at that point.
Oh well, I still haven't given his mom any grandkids besides a step grandson ;-) So don't listen to my advice :-D
