I can't recall that I have myself other than some really cool performers at Fisherman's wharf. DH did take a picture of an woman walking in Red River, NM. We both felt very weird doing it but she looked like the so called "mountain people" and we were in the mountains. We just haven't shared the photo, but it did remind us of a funny night walking in the cool mountain air.

I personally can be very weirded out by strangers so I try not to be weirding anyone out. I would probably ask if I had the nerve.
