It's kind of funny when you go to Alcatraz. It's cool to see, walk through, etc. But it really has the feel
of a cheap castle made for criminals.
I'm pretty sure they were thinking - how secure should we make this with all that crazy cold, high current water to swim across? No need, they can't swim it, and if they did, well, good on them I guess. Yeah, good point, make it crappy, save some costs. Okay, bid accepted.
