Yeah man, there are some good places, a bunch of us just got back from evans today, next sunday, there is a naches trip.
Evans creek orv is just outside of buckley, I'm in Bellevue, and it's closer for me to go there than walker.
Naches is in a similar initial direction (167 south to 410 east), it goes across to the sunny side of washington. I haven't been yet, but I hear it's fun.
There's also some buzz about a trip to tahuya soon. I don't know anything about what it's like or where it is, I just see that the gig harbor/taco guys talk about it a lot.
Hope this helps!
