'Kay, the tee-shirt is not a call-back to a previous
AdTwi comic... So a quick Google search shows several real-world Sandpiper Shores locales, including an elementary school in Fla., a motel in Louisiana, and a road in Indiana. So what's it all about, Alfie? Maybe the artist just looked in his/her closet and sketched up the logo on the front of their fav souvenir tee. Am I overthinking it a bit? Perhaps.
Of course, a filly's not
