Chicago

Hi lovely mid westerners. My name is Rose and due to a job I've taken I must relocate to Chicago. Can anyone recommend how I can still be involved in permaculture or urban gardening in the area?
I won't have any property where I'm going I have to rent a room but if there's any organization you can recommend I am all ears. I have never even visited Chicago!   Any beautiful places nearby that you can recommend I would love to hear!
Thank you
Rose
