I've been before. It is fun, the weather was terrible the time I went so I didn't hang around for super long. There were a lot of birds for sale and I would anticipate there being a ton this year. It was a lot of fun walking around seeing all of the show birds as well.
The Lebanon show is my "must go" show. It's a large show with waterfowl, other poultry, and the junior show all in different buildings. The sales pavilion is an open shelter, and many vendors set up outdoor sales areas at their vehicles as well. I've seen exhibitors from as far away as New York state. With Michigan, Ohio, and Kentucky shows cancelled, it's likely to be even bigger than usual. Definitely worth the drive!
I hope to have a few birds ready to show--hadn't concentrated on keeping them show-ready this year because thought all was cancelled. Between molts and broodies, don't know who might be decent.
Thank you both for the responses --- I think I'm going to go. If nothing else, it's a day spent with chickens, and that's never a bad thing, right?
