Where is the show place on the fair grounds

There is a "Washington State Fair" app that shows you where everything is. Only advice I have to offer

If you mean the grandstand where evening concerts take place, it's between the red and silver gates. There is also a "street" or thoroughfare called showplace way that runs along the outside of the grandstand. As someone mentioned, there is a free app available that gives all the details of the fair events and the fairgrounds.
