That's awesome, Laura! Unless you reacted with visible surprise, I bet she didn't even think twice!
I've shifted my outdoor wardrobe over mostly to female clothes, so I'm presenting as female when I climb now -- which is awesome. That was something I was still working on when this thread started. It's definitely not "glam," but I typically get "ma'amed," so that pretty much rocks. The main hangup I have is with getting done with laser -- wearing makeup in the mountains is kind of lame.
