No, I have not been to his barn, and I don't believe that I had been aware of it, either, until now, thank you for the link, too bad it is only opened on the 3rd Sunday of each month, very odd hours, one would think that it would open at least every weekend, I cannot think of any other museums that have that odd kind of scheduling.
Anyway, I would love to visit, hopefully, the days will be extended for being open. Not sure if I can be there, to make the current schedule.
