An idea... If your worried about food availability, take advantage of the easiest food storage solution. Get non-modified seeds, potatoes, etc. Stuff that will blend in ok. Go plant in in some fields in your AO. Not like the local park. In the woods if they will take shade, in meadows, where you go to FTX. Make sure its good hardy plants, not stuff that will smother.

Potatoes are great for this concept, a 10 or 50 lb bag can make a lot of gut fuel. They go in lots of soils, they are short, dark and will spread if you don't dig them up. All you need is a spade and knowing the area they are in and you'll have atleast something to put on the plate, raw or not.
