In case anyone is frantically trying to find an elusive summer weekend date, Crag Rats Hut in Hood River has an opening on Saturday, June 18th (it was previously booked by me and my fiance, and recently was released since we made new plans).
Just thought I'd let everyone know since summer weekends are hard to come by! The venue is absolutely amazing and we're sad to have to give it up! 
Hopefully this is helpful to some of you.
