My wife and I went there yesterday. Great people, great layout!! My wife (who's not a train fan) went around the layout THREE times, as she discovered more and more detail that intrigued her.
I enjoyed talking with Tom Elesh and his wife Vicki. Tom Jr. (who wired the layout) was a help to me on signals, and daughter Ashley does a great job of showing visitors around.
We live just about 30 minutes north of there- in Perry OH, so you can bet we'll be going back, and taking friends and grandchildren.
