We stop at Centralia almost every year on the way back from ECXC...its pretty much a tradition.
Did you stop by that section of hwy that cracked down the middle, and now looks like a steaming mini grand canyon?
TJ next return trip from ECXC You should make time to stop by the Pionner Tunnel and take the Mine tour, If my X is parked out front, I could be your guide! lol . . If you get enough ppl to do it, call ahead, and you could probably get a group rate for it.
