^ it still seems a little tacky to just tack it on.
get it?
but i suppose if it's invisible from the grant/millennium park vantage point, and it's done as discreetly as possible (like tucking it into the NW re-entrant corner), i suppose it might not be the end of the world.
i still don't like it on the surface, though. i'm generally not a fan of any of these gimmicky, tacky amusement park attractions being tacked onto some of our city's most noticeable skyline landmarks.
