Wow, I'm shocked to see someone from Tri-Cities on the PPK! I'm from the area as well, but I'm moving to Seattle in 6 months.
On topic: I would prefer Vida Vegan Con in Portland, but I'm sure VegFest is fun as well. Let us know how it is if you go!
Sorry, this was a few weeks ago .. but I did go (and I drug a couple of Seattle friends out with me). I've never been to a "vegfest" before, so I didn't really know what to expect, but it was good for a few hours fun. I got a ton of free samples and got to try some things I probably wouldn't get to otherwise. So, all-in-all, glad I went!
