This is a really cool sign. It could be that I'm just projecting, but the materials that make up the holder for the actual wooden sign (which utilizes the image of the St. George's Church bell tower to represent the park) are brick, of which the bell tower is made, and what looks to be sort of vaguely similar to tabby, of which Fort Dorchester is made...and it's all crowned with a railroad tie, which has no significance whatsoever, but it sure looks cool.
