The OP is from NorCal, and there is a town called Auburn up there, so I'm guessing its in Auburn, CA.
For those who don't know Auburn, there is a great little brewery there called the Auburn Ale House. They have a number of good brews, but my favorite is the Hop Snob IPA. The last time I was there, I bought a growler just so I could take some home with me. They also have awesome salmon tacos.
Sounds like a cool event. Might go check it out, since the 2.5 hour ride up Hwy 49 would add to the fun. I wonder if I could pad my Givi top box and stand the growler up in there...
