The Oregon High Desert Grotto publishes the Oregon Underground newsletter. It's free with a membership to the grotto. It comes out seasonally, or as time permits. Typically, the newsletter is sent out in a PDF format to all the members by email because manually printing them and mailing them is cost restrictive! Take a stroll through this thumbnail version of Issue 33 released in 2011.
