Ralph,
I see Rene nearly every day each summer., during the couple weeks I'm there. He's one of my tier heroes. He checks the water at the headwater of The Ranch nearly every day and stops in at the Trouthunter for iced tea.
Though famous, he's very approachable.
I usually, correctly or not, refer to them as "emergent" duns......beyond an emerger, but not yet a dun.
