David, as an 8x10 user I was going to say something similar. In an earlier unrelated thread I touched on the topic of "novelty cameras" as being an excellent way to break the ice with strangers in public.
If I approach someone with an 8x10, or even a 4x5 Crown/Speed Graphic, I'll often get an enthusiastic response that I'm certain would not have otherwise been the case with any other more normal looking cameras.
A huge 8x10 is sufficient enough of a novelty that curiosity almost always overcomes reluctance.
