  • Occupy Chicago protesters on LaSalle Street in late September

It’s great weather for a protest. And Chicago is having one, as protesters are assembling at this hour to “Take Back Chicago,” a theme that must be confusing to Mayor Emanuel, who feels he already did.

Protesters will be marching from five sites to the Art Institute’s Modern Wing at Columbus and Monroe for the main rally, expected to begin at about 5:15. The Modern Wing is the site of a reception this evening for the Mortgage Bankers Association, which is convening at the downtown Hyatt Regency this week.

Organizers are predicting 7,500 protesters. Their press release also promises key visuals for media, including marching bands and 12-foot-tall corporate welfare-king puppets.
