Have I been there? Dude, I was on the USS Michigan at Subase Bangor from 1990 to 2005. Yeah, I've been there. (Not trying to be rudely sarcastic, just ironic.)
Haha, its a neat place. I dont know if they had it when you were there, but the submarine/torpedo that the Japanese used was kinda....creepy. I have a pic of me under the celest ( i think thats the name of that big white deep sea sub out in front) of me underneath it "holding" it up. I actually stumbled upon that place my mistake. My scout troop was going out to fort warden (its up in port townsend) and the hood canal bridge was open, and being that my dad works for WSDOT i was what the hell they never open this bridge, so i called him up and he told me the only reason they usually open it is for subs, and low and behold about 10 min later, a trident rolls by. Very aweinspiring, knowing that one boat had the power to level over 1/2 the world. I took some neat pics of it, however they arent digital
So anyways, with the sub sighting, we decided to detour over there and have a peak at the base. If you get a chance, head into seattle. Down on the water front, around pier 49 or so, there is a big musume dedicated to sea vessels and shipping etc. They have a lot of neat stuff in there too. Also another cool place to go is down in Astoria Or. They have a musume down there about the columbia river and all the stuff that has happened with it. If you want info on either one, i can dig it up for ya.
