there's a submarine in my parking lot

Okay, okay, it's just the sail, not the whole thing.

USS Triton, the first submarine to circumnavigate the globe underwater. Decomissioned in 1969, scrapped 2007-2009. This (and the reactors) are all that remains that isn't razor blades.

Located in Richland, WA, dedicated on Veterans Day 2011.

No general access inside, which is too bad, but there ya go.
