On the Usenet group rec.outdoors.rv-travel, a bunch of posters living in PNW started having group camp outs (aka PNWCO) and I believe the next will be PNWCO #5. Everything from tents to BulgeMobiles, everyone from "retards" to young families, lotsa pets, even occasionally some rats;) .
If interested, go to dejanews.com, find the group and use the search engine to find PNWCO, sort results by date and read about it.
Even going to have some "RORVT PNWCO" hats.
