Lucasville, Ohio http://ohio.hometownlocator.com/oh/scioto/lucasville.cfm also you can do a google search for the area. I've only been to one swap meet there and that was several years ago. Not sure if I'll make this one either. Lebanon, Ohio is over in the south west part of Ohio, while Lucasville is south central state, several counties from Lebanon. If that helps.
I don't know about a show in Lebanon-but there is a swap in Troy Oh at the fair grounds-April 30 and May1-looks like it will be everything from chicks to zebras, plus some
regular swap stuff-tube socks and old dishes!
