Are they the same weekend?
Does anyone have a link to the PDI's website? I definitely intend to support the upstart organization.
If their big Vegas event is the same weekend as the Olympia, I would attend both, but suspect that the Olympia would have the slightly better Expo this time around.
Howie - I agree that the distance between the event venue and Expo at the Olympia makes it very problematic for visitors. The Olympia Expo was smallish, too...I mean, there were 'enough' people, I reckon, but I was able to see the entire thing in about 45 minutes.
