You are a young, well-paid executive working for the Boyle and Charles Oil Company. Something has gone very wrong at one of your storage facilities in the northern United States. Your boss told you to get your rear end (and she didn't use the words "rear end") up there to, "Find out what happened and make sure it doesn't happen again."
As you stand stunned, your mouth hanging open, wondering who will feed your fish while you're gone, she asks, "What are you standing here for? The file and your airplane tickets are on the secretary's desk. Get going!!"

You know if you do a great job you'll get promoted, but the last person who wrote a poor report got fired. The company does all it's investigations using the scientific method and writes all its reports in the lab report format.
It's the 29th of November so you grab your coat and the spare clothes you keep at the office just in case you slobber spaghetti on yourself at lunch. In front of the building you see a cab waiting so you jump in.
