Hi Hobby Shooter,
I'm not sure how you define classic bikes, but they were all pretty old! LOL I think there was one brand new Ducati, probably related to the fact that Ducati was one of the sponsors. I think just about every brand I know of was there except there were no Vincents. One guy brought his home made scooter that was quite bizarre looking. I had to google the brand name "Klausmann" which turns out to be the name of the guy who built it in his garage. Pretty funny.
They must have had over a hundred old bikes there and a lot of art photography too. The place is at 420 NE 9th in Portland, OR and the show will be there tomorrow too if you want to check it out.
