Did you try it through the North Central Division AFMars web site at http://www.afmars.org/marsforms.shtml
While it says that it is for
USE BY ONLY RESIDENTS OF IA, IL, IN, KS, MI, MO, MN, NE, OH and WI.
since you are from Massachusetts, you might want to drop them an email at email@example.com
to find out where to sign up for your state, which would be in the Northeast division.
