I was raised to believe that a vacation was not really a vacation until you had purchased your obligatory T-shirt with the screen printed name of your current family-friendly locale likeWilliamsburg, Va, or Gettysburg, PA.  I have personally taken time out of my childhood to agonize over whether or not I wanted the t-shirt with the canons and the sabers or the one with Abraham Lincoln with the Gettysburg Address scripted behind him.*
