There is a cool page called Forgotten Chicago on Facebook. I made my first post about a tear down in Lincoln Park and it has made quite the stir! Over 650 reactions and hundreds of comments. My favorite comments are from people who lived on the block or in the actual building. I have had people email me in the past about buildings I have written about and tell me their stories. So cool!
