I am one of two full-time park rangers who deal with the public. Of the two, I am the one who has reproduction uniforms and gets to play with the 1942 Willys and the BREN gun. We cover 1896 - 1956 so I have lots of leeway when it comes to dealing with history. I depend heavily on volunteers to help me flush out the living history demos that are so popular. Like these folks, my volunteers are amazingly accurate and dedicated to honouring the common soldier.
Oh, and we have the oldest lighthouse on the west-coast (turning 150 this year).
