No one will ship spores to California.
I've looked. We tried shrooms once on a whim, in Amsterdam, and while it wasn't that interesting a trip, it did have the side effect of eliminating my wife's OCD for almost a full year. I wish they were easily available. I've even considered driving to that "church" in Oakland to get her something. I don't otherwise have the right kind of friends (or they are quite discrete about it despite my having mentioned it).
