Wanted: event space to accomodate 400 people for an auction

Community Warehouse is looking for an event space for our Chair Affair auction in April 2010. We need a space that will accomodate up to 400 people and space to show our auction items. An ideal space would be close in NW or N/NE Portland and allow us to use our own caterer.  A warehouse type open environment is ideal.   Please send any recommendations to Roz Babener, [email protected] or call 503-329-5588
