This cache placement brings you to Olive's Neighborhood Garden or "Garden For the Hungry" at the corner of Ainslie and Laramie in Jefferson Park.

From their Facebook page:
An award-winning garden in the Jefferson Park neighborhood of Chicago providing handpicked produce for local residents in need. Deliveries to the pantry are made on Sundays.
Description
The garden is situated on a previously abandoned lot of state owned property on the edge of the Kennedy expressway on ... the north side of Chicago.
A brief history on how the garden came to be:
The Jefferson Park Community Association wanted to do something with the space for some time and in 2008 the idea of a garden there was mentioned to Heinz Nogly a scout leader in Cub Scout Pack 3963 which meets at Eden Church which is just a block away from the space. The idea was passed along to Andy Brecklin, a leader in Pack 3963 who was also involved with Boy Scout Troop 840. Andy, who is still heavily involved in the upkeep and organizing for the garden, then passed the idea along to his son who went on to start the garden.
There is no need to enter the garden to search for this cache. Please be respectful of the garden and its neighbors as you hunt.
There is always some way to leave your mark on the log. Any log that indicates the finder did not sign for any reason (no pen, log full*, scared off by a pack of Cub Scouts, etc.) will be deleted.
* If the log is full, squeeze your name on there somehow and please mention it in your log so I can maintain! Thanks.
Update 6/10/2014:
Imagine my surprise at receiving the following email:
Good Morning,
I understand you keep a little cache there, which is cool with me and the garden. I spend a lot of time there and am the goof throwing hay around on Dec 29th in the cold and snow.
First - I'm looking to safe guard your cache. I'd hate to dig it up and throw it away in ignorance.
Second - I'd like to sloooowly introduce it to my Scout Troop (Troop 963) down the road. I figure geocaching may be a way to set goals and get them moving on some of these camping trips we have
I look forward to hearing back from you.
Andy
