Seriously? Isn't anyone else just a little pissed they moved it back to Vancouver? Last time I checked, KumoriCon was billed as Oregon's main anime convention. Hate to break it to you, but even if it's right across the river, Vancouver is not in Oregon.
Have it where you (I'm not sure who "you" would be, whoever decides the location I suppose) like, just stop calling it Oregon's convention. Washington has their con, it's SakuraCon, yes it's in Seattle miles away but they've got theirs. We don't need a SakuraCon part two. I find it hard to believe they couldn't find another meeting place/hotel or work with the downtown Portland Hilton to keep it in Portland. Extremely frustrating...
