Just take a walk through the stationary area. Everything says "Happy Fourth" or 4th of July. You don't see a lot of "Independence Day" there. It is almost as if "Independence Day" is the "Christmas" of summer, and "Happy 4th!" is it's "Seasons Greetings".
Water everything down of substance and that matters in America.
And while we're at it, let's get rid of "Merry Xmas", too....We've probably got a whole generation of kids running around in this country who think "Xmas" is the birth date of a black 60's radical.
