From Alderman Mary Ann Smith's website:
"Block Clubs are the heart of the 48th Ward. They give strength to the residents and, through their representatives, advise Alderman Smith on a wide range of issues including zoning, planning and transportation."
For those of you who live in the 46th Ward, you probably have noticed your Alderman feels otherwise. If you are new to Uptown and are wanting to find out which block club you should belong to, check out this handy link from the Uptown Chicago Commission here.
