Creative Gardening

I have been looking into ways that I could plant a garden without having a lot of land to put in on. I have been studying up on different sized planter boxes as well as thinking about container gardening. Stephen has also presented the idea of hanging smaller blanter boxes outside the window. Does anyone have any other thoughts for how I could have a garden without a lot of land? I really want to have one this summer, but I don't know how much room we will have since we are moving. Also, Elena, so far in our caravan we have Mom and Dad, possibly Nathan, possibly Stephen's brother and family, and anyone else who would like to come.
