Well, I guess that I should add my 2 cents worth to this post. I grew up on a farm and we had a garden near the house and the large fields with the commercial crops of Tobacco, Soy Beans(Actually its SOYA BEANS), Corn, Peanuts, Wheat, Water Melons, etc. The one thing I learned from that garden was it was a lot of work. Tilling, Fertilizing, Planting, Watering, Protecting it from animals and insects and thieves, and harvesting the crop when it matured. I have about an acre of land that is my side yard and I could till and plant a garden there if I needed to. But, I don't want to do all that work at my advanced age. With that said, I have both Heirloom Seeds and Regular Seeds just in case things get bad enough. Night time is going to be your worst enemy because that's when the little critters come out and eat your stuff. You might try installing several Solar charged Motion Detection lights around your garden to scare off the critters. If they get used to the lights coming on the lights might not be very effective but if thieves come around, the lights will probably work great because they will think you saw them and turned on the lights. I'm all for you folks creating gardens and applaud you but you must understand that its a pain in the ass.
