Lye source in North California (Sonoma County)?

First of all, I did a search and couldn't find what I was looking for.

I live in Sonama County (Santa Rosa) and if at all possible I'd like to get my hands on some food grade lye today. I have a last minute request for pretzels and prefer to not make a mess boiling them with baking soda. Anyone have any ideas where I could pick some up around here?

Thanks a ton,
