Bill – The club has riders with a lot of different interests. Not to over-generalize, but the ADV riding crew doesn’t really attend breakfast. (I know there are exceptions, but mostly true).
The best way to meet the ADV riders is on an ADV ride. Washtenaw is a good one.
Also, sounds like your cottage is right on our Oakland ADV track. It moves around a bit, but all of those roads have been on the track previously. That one is usually in the fall. Great roads up there too!
