KWM, Parade starts Saturday, but unless you are registered, there is not much you can see or do until Sunday and the Concours. Also, it is my understanding that if you have your PCA card with you, you will be able to get into the Goodies Store Sunday afternoon. . . But don't quote me on that.
Pleaswe keep in mind that this is an advanced registration event. Do not expect to be able to walk up and, pay your money, and go.
