Its like they make up for our bland architecture with over the top designs for street furniture. Can't say i'm a fan. I'd prefer something more subtle and clean like the new york proposals. Keep them clean, easy to clean, simple, and use great typography for the signage. Nothing screams boring like using Arial with no typesetting. At least use helvetica with some proper typesetting.
The CBS stuff looks pretty bad, the clear channel looks alright. I would say the astral looks best but it just seems like there is just too much detail and useless stuff tacked to the sides.
