shit...they are all marching towards Michigan ave, which is a major N/S road in the city. Traffic is going to get ugly as they march north on Michigan. Fortunately its late. They are apparently marching north about a mile to the area north of the river, called RIVER NORTH, which is where all the clubs and restaurants are. Those places may still be open.
police station where they took the people they grabbed in the south loop.
