yeah, the expo's are now always like 1 county over. Monroe in Snohomish County in the Spring and Puyallup in Pierce County in the Fall. they had one in an actual suburb - Renton - but that was like 4 years ago and they haven't been back near the city since.
really?! that's awesome. the Serpentarium/Reptile Zoo is pretty cool and the Fer De Lance and Pit Viper above are from there. i'm sure your Rattler probably made it out to a past show.
Edit:
i got a discount and only got to hold one for $4. took a pix too!
