I've done alot of AT hiking with a lesbian friend. It's not at all obvious that she's gay except when her partner meets us. If people had to guess which one of us is gay they'd probably get it wrong (I'm the one who starts the hike with unshaved legs). In fact, once we were chatting with a couple of male hikers on the trail and they asked her if she was married, didn't ask me (she wears rings and I don't). The only time I get upset is when people ask if she's my daughter.
