So I got to thinking, "surely there is some touristy submarine thing set up somewhere." And I was right, because this is Murrica. California and Hawaii have some places to sub. To go submarining? Not sure what the verb would be, but check this shit out.
This one looks like a damn yacht.
Not even a slight resemblance to a submarine.
If I'm going subbing, it's going to be in a dirty, black, old navy submarine, that could be faulty. I like the potential danger in it.
