I received this and am passing it on. Note that the name is very close, but this is not the same as the Northwest Model Expo that is held in February.

Hello -
You and your club members are invited to attend the Northwest Model Aircraft Expo on August 1st and 2nd at Yard Birds Event Center in Chehalis, Washington. Cost for vendors is only $25.00 for the weekend - or $15.00 for One Day Only. However; early birds...registered and paid by July 3rd...will get the whole weekend for only $20.00!

The Expo will be indoors - but there is lots of space available outside for demos and various aerial acrobatics. That same weekend the Chehalis Airport will be hosting a free Air Fair (with lots of military and civilian aircraft) - so expect a lot of aircraft enthusiast from all over the Northwest.
Application and Rules forms are attached. Fill out - mail back (with payment) - and you're set! Please distribute this information to all active club members.
