Ever clean out the salt water intake tunnels of a power plant? I heard it smells nasty (kinda like rotting dead body nasty), its dark, which you stated you liked with a putrid smell, its cramped which you also like in a job. Ive heard of all the above conditions from my husband who is a shift supervisor at the bridgeport, ct powerplant. What a wonderful time for you to experience the job but in a new england ever approaching winter! Scuba suits are required at some point in the job!
