Aburn Hills show in may?

looking for info on the VW show in may. i've heard it's the weekend
of the 15th/16th, but i've heard no other details. i'm hoping to
find a bus there (assuming people sell their stuff at these shows...
having never been to one i don't really know how they work) but i
need some specifics.

if anyone knows anything, please email.

thanks in advance!
