A few Saturday's ago we took Julius to the Naval Undersea Museum. It has everything Submarine! A mock control room which is where Daddy works in his sub, so we enjoyed playing around in there!
These are the bunks in which Daddy spends his sleeping hours...usually only about 4-6 hours at a time. However there are usually drills that rouse him every 45mins to a hour :) So, first he has to get comfortable in a 5' some odd inches bunk...

I'm 5'2", he's 6'1" so the bunks fall somewhere between us :)

The hatch would fit Julius just fine...Daddy not so much :)

It was really fun to see what Daddy works on!
