About to buy land...

Hey all, how are you doing?

I'm about to buy a small and cheap piece of land (0,39 acres) about an hour and a half from where I live. Still a student and planning to work for a while in the city after that, so I won't be able to tend to the place that often.
My idea is to set up a system that could take care of itself, with me providing the minimal amount of work. Here is a photo of the place taken in October 2011:

You can clearly see the kind of swale going around the property, but in 2012 it looks more like this:


Ideally, I'd like to go there once a month to pick a car load of greens/vegetables/fruits. It's in USDA zone 5a or 4b

Eventually, setting up a small living fence around the corner seems to be a good idea... although the electric lines passing right through may cause problems.

So I guess a kind of food forest would be best for that scenario? What kind of plants would you recommend (fence or harvesting)?

Thanks and good day!

Here is a very good list of vegatables that you can grow.

Take alook at my Boston,MA backyard garden. See if you get any ideas and leave a comment or two.

if you plan to build on the land eventually check with zoning and power co and see if you actually will be able to BUILD on the property..the power lines could prevent building and is it large enough to build on according to the zoning?? if not..wait for something else..some places require an acre to build on and you can't build under power lines

otherwise sounds like a plan
