What is this Bicycle show/Swap meet?

Something called the Classic Bicycle Show and Swap Meet is happening in Ann Arbor on April 27th! I'm excited but I just realized that I have no idea what this is or what to expect. Can anyone give me some insight as to what this is? Could I expect to find good deals on bikes (used or new)? Could I unload some of my old bikes I've acquired over the year that don't fit me and are in...moderate shape?

Thanks!

In seattle, our swap meet is yes; filled with good deals on whole bikes, bike parts and bike gear and clothing.

Not sure what yours will be like.

and yours includes a bike show too! that ought to be nice

If you have purchased a bike at a swap meet/bicycle show, what did you purchase? Was it a good deal? Used or new?

Thanks!
