If you want perch in such quantity and size that there may be enough for dinner, pop the $5 for parking (with a validation ticket from the parking office near door 8 of the garage) and hit Navy Pier. The only thing going on at Montrose now is browns and coho (and a few steelies), mostly lakeside and mostly by powerlining. See Westwind's posts re: how terrible the perching has been this winter in the harbor. But hey, only about a month and a half until the jumbos come back lakeside--yeehaw!!
