Wrigleyville is no stranger to large and rowdy crowds, but many business owners there are unsure of what to expect from Thursday’s anti-violence march. Organizers have said they hope to “redistribute the pain,” meaning they hope the likely hassle of the march for North Siders will focus attention on the violence, poverty and lack of resources on the South and West sides of the city. Marchers are expected to travel through Lakeview — west on Belmont Avenue from Lake Shore Drive and then north on Clark Street — before arriving at the Friendly Confines where the Cubs will be playing the Padres in a night game.
