I don't hunt for CDs in public, but I see them sometimes. I've unintentionally come face to face with CDs in stores a few times. Over the years I've learned to treat it as a non-event.
About a month ago I ran into a couple at the grocery store (a man and a woman standing in front of the frozen food section). In a friendly, civil way I had to ask them to move a bit. It turns out that the woman I was conversing with was a CD. She had no fear of the encounter at all, and of course I interacted as I would with any fellow human in a grocery store.
Things have changed IMO. About 20 years ago I came (unintentionally) face to face with a crossdresser at a store. She looked very shocked because she could tell by the look on my face that she'd been clocked. I looked away because I felt that I was invading her space (by the look on her face). At that point she fled the scene quickly!
My first sightings and encounters with CDs in public took place about 40 years ago.
