Sorry, I am not aware of Sobon's yellow covered book, only the biggie he wrote w/ Roger Schroeder.
But I'm proud to say that we have been accepted to tour the barn of the somewhat private owner (horray!)... the other barn (the more dillapidated one) is likely a shoe-in and I'll know on this one real soon. The somewhat private lady is a little concerned with the ammount of folks wanting to access the second floor and she wants to make some room/ clean up a bit... but she'll take 10 of us. Her 2nd floor is more sturdy that the other barn's that I said was like bouncy staging.
Housewright:
I guess we have the go-ahead for an event/visit, etc... do you think the two CG barns will be enough for the day, or should we try to schedule some other CGs. They're all within 20 minutes of each other...
I'll have to re-examine my photos, but since the discussions on the Shirley barn and what constitutes a true CG frame, one of the 5 CGs here may just be an interrupted plate frame and not dropped girts...
