Marines Bag/Backpack Thingy

I sent away for the duffle bag here http://www.marines.com/page/usmc.jsp?pageId=/forms/processLead.do&flashRedirect=true
and got this in exchange. But it came next day FedEx. Scared me cause it said US Gov on the package. They want me to go see a recruiter. No calls or nothing just a letter on how to sign up and how wonderful being a marine would be for me….I think I am too old (Thank GOD)
