You know the economy must still be suffering when Wawa rolls out 4.5 ton hoagie for Hoagie Day, rather than trying to outdo the one-and-a-quarter mile hoagie it assembled near the Art Museum last year. But it must not be too bad, because they’re still serving up huge sections of the monster sandwich to the public for free. All you have to do is show up at the Independence Visitors Center anytime from now until the thing’s gone.
