It's a two day drive to get there from the Seattle area, but I am in fact scheming to do it next summer. Been wanting to do it for years. I could do it in one killer long drive, but won't. I'll be able to swing through Spokane and pick up my brother, assuming he can get the vacation sorted out.
And the on-loan exhibit will still be there. So thanks for the heads-up
