It is in a fenced area ( 6 foot chain link and 3 strands of barb on top )and locked up when the museum is not open. Was closed when I stopped so had to get pics through the fence.
DP- as you are going through Chehalis it is on the south side of I-5 as you make the corner to head north out on the south end of town. You will see a big US flag and a Huey Cobra on a post mount.
