Today is National Hat Day. Why I'm not sure. But it is. And the good folks at Arby's want you to help them make the 10 gallon hat "America's Only National Hat" Some might remember that all Arby's used to have the 10 Gallon hat sign as their logo outside most locations. I still remember the old sign at the South Westnedge Arby's in Portage...all lit up and cool. Some places still have the old Arby's signs.
