Harry Truman (not the president) is associated with Castle Rock, WA. Stayed at his home and didn't evacuate when Mt. St. Helens went. Presumed dead in the blast.
Anon answered a post of mine a couple of days ago saying 10 Mountain (at least) uses Truman when referring to Castle Rock.
Anon said 10 Mountain guys were tweeting about Truman, so he figured we're at least at Red4.
Not sure, anon didn't say, but maybe Castle rock is a training area.
Some Wiki stuff:

Truman Trail and Harry's Ridge in the Mount St. Helens region are named after him.[36][37] The Harry R. Truman Memorial Park was named in his honor in Castle Rock, Washington,[38] though it later was renamed Castle Rock Lions Club Volunteer Park.[39]
