There is a Bicycle and minibike show and swap meet at the Washtenaw Farm Council Grounds at 5055 Ann Arbor/Saline Rd. on Sunday May 1.
Gates open at 8:00 a.m and it closes at 3:00 p.m.

In addition there is an auction that begins at about 11:30 a.m.
If you have any old bikes or minibikes you can put them in the auction for $10. The earlier you get there the earlier it sells.

The bicycle show is in the front cinder block building and the minibike show is in the last building at the far ends of the grounds. The auction is toward the back of the grounds.

The weather forecast is for rain but there are a few pole barns full of swap meet tables.

Here is a link to the website.
