So I think the folks should see and find it with no problem. And Dearborn is a nice street for taking a stroll. 'Lotsa' cool buildings and not as crowded as State St. [But I'd walk on the WEST side of Dearborn, its more sunny and a bit warmer ;-)]
Plus, IMHO it makes more sense to have an anti Fed Tax (and spend) Tea Party AT a Federal Bldg's Plaza. but that's just me :-)
There are advertisements in over 100 northern illinois newspapers with the Daley Center address running this week, and you think it is no problem to move four blocks with those directions? You guys better plan something or you will look like absolute fools.
