The Western States Republican Leadership Conference website is at http://www.wsrlc.org
The registration fee, presumably for all of the days, is $250. That outragous fee certainly represents the policy of inclusion that the Republican Party follows. Of course, I'm sure the last thing the Republicans would want is dozens of people to show up and heckle their greedy policies and cause disruptions as they scheme to "win the west in 2004", so DO NOT DO THAT.
From 6pm - 8pm on Friday, June 13th there will apparently be a "Reception in Downtown Portland", presumably where their special guests will show up, so once more details are confirmed regarding that location and the attendees, you might feel free to head down there and shout encouraging words to Mr. Bush and his cronies regarding his destruction of the environment, slaughter of innocent people, redistribution of money from poor folks to rich folks and whatever else they do that you take joy in.
