If you end up doing the PO box thing then do it with the money you were gonna use for the sand, and me and a couple of other guys here will throw in some other stuff your gonna need along with the book. We can send you out some sand, some backround, and whatever it is you need but cant get a hold of. Ive got driftwood, sand, gravel substrate (natural), fake plants (I think) and all sorts of other stuff that Ima hafta get rid of soon and Id rather send it out to you who needs the stuff than some socal kid that can get the stuff anywhere.....
