[alt-photo] Any places in the SF Bay area to see gum prints?

[Denny]

I think I'm getting hooked on printing gum (thank you Keith, Christina, and all the other gum printers who pointed me in the right direction when I asked about gum over platinum) , but I've never actually seen a "live" gum print.  I might be doing a trip to the Bay Area soon, and thought it might be an opportunity to see what's possible.  Any suggestions?
Thanks,
Denny
