Never let anyone tell you there isn't room for a garden.  

Wherever you have sun, you can grow a container garden.  I also use this spot to start seeds which I then transplant into my community garden plot.  When starting seeds you need to keep them evenly moist and keep an eye on them...and also get excited when the first green leaf appears.  So its best to do it at home, even if its on top of a truck cap!  Then you can transplant them elsewhere--or into a container in the same spot!
