Guess it depends on who you know
I love the irony: You can see pix of nuclear subs on Google Maps, but just try to get a pic of The US Naval Observatory, site of the official residencia of the head of the fourth branch of government, Veep Dick "Dick" Cheney. Check it out--the grounds of the USNO are pixellated in a valiant attempt to protect a site vital to national security.
But wait, it gets better: Cheney's posse overlooked MapQuest.
Ya gotta love it.
Enjoy the sea voyage, man!
