I will be visiting Chicago with my family (wife + 5 amp; 7y/o kids) next week and, among the touristy stuff that we have scheduled, I would like to know if it's safe to walk around Lincoln Park, Old Town, Wrigleyville and Wiker Park-Bucktown neighborhoods during the late afternoon and early night hours using the CTA system.
