Where in WA are you? I live in Tenino if you know where that is, it is about 30 minutes south of Olympia. If you have an IH, there is a huge club called NW Binders, but is looks like you have a Yota. I have a large group of guys I usually wheel with, most of them are in northern oregon, but there are a few others all over WA. Check out www.nworc.com, and send an email. I haven't gone on any of the runs lately since I am rebuilding my IH and retired my Nissan to a daily driver only, but I hope to have the IH done in a few months.
Once I get my truck done we will have to go wheelin. If you check out the site I posted before, most of those guys are from Portland and Troutdale, so they aren't too far away from you, they have some really good wheelin spots around there too.
