Do you stare or double-take when you see two girls (or guys) holding hands?

I've been hanging out a lot over the last two weeks with someone I've know for a few years in school. Today we went on what was, I guess, our first real date. It was a day hike up to the top of a place called Blue Hills outside of Boston. Because it was a beautiful day, the trail was pretty busy and so many people stared at us, or did the classic double take. The only thing I can thing of to explain this was that we were two girls holding hands. How do you react to seeing two girls (or guys) holding hands in public?
