Diana,

Oh, those people do exist. Eric Christenson is one, Ron Parsons is
another. Peter O'Byrne and Jim Cootes are probably like that - but I've
only communicated with them by email, not in person. It's really
remarkable - I was never able to even remotely stump Eric Christenson in
Peru - no matter what orchid I asked about.

Thanks for the response, Eric. I get it. When you are taking the photos,
many are noids for you until you research them. Makes perfect sense. And, it
does make me feel a tad better! I'd hate to think there exist walking, photo
taking encyclopaedias!
