Rik Smit's Swap Meet at the Lebanon, In county fair grounds is March 7, 2015, with an auction on March 8th. It's about 20 miles NW of Indianapolis. There is usually a good turnout, lots of parts and bikes for sale. Apparently the auction was good last year; unfortunately, I missed it. There are sometimes a Bridgestone or two for sale; so far, just the smaller ones. It's for Japanese and European bikes, so there is limited Harley stuff cluttering up the place.
