I know of at least one other member here who's a member there. For his privacy, I'll let him mention his name, but he once invited me out and I thoroughly enjoyed it. I went on a Monday afternoon, and there were about 6 people there, including a husband/wife duo with mil-surp rifles and practicing pistols, an elderly gent with a chronograph and a new rifle, and a few others. We were just on the 100 yard course.
I've suggested, Cougfan, on the "Moving to Portland" thread in the Rallying Point section, that, since they do have a 1,000 yard range, it might be a great place for a metro Portland Appleseed shoot. Now that you're a member, maybe that could be easier to talk about/plan.
