Found this story on RateBeer: OBF Announces Oregon Beer Week.
The Oregon Brewers Festival is pleased to announce "Oregon Beer Week," a weeklong celebration of craft beer by Oregon’s specialty breweries. Oregon Beer Week will begin July 23 and feature a variety of special events taking place at craft breweries throughout the state, culminating with the 18th annual Oregon Brewers Festival (OBF) at Tom McCall Waterfront Park in downtown Portland July 28 through July 31.
"Throughout the state" seems to be a bit misleading, though; from what I can tell, they all take place in or around Portland. Even the one from Rogue. Oh well.
