Cache location ideas

[Sixpotter]

Starting to build a nice basic level of preps and am struggling to think of somewhere safe to cache them. All in eggs in one basket at home at present as I would be planning on staying there if anything should happen but I would like a plan B.

I just fear someone seeing me digging or the land being fenced off and turned to building site etc I live in a busy part of Essex but could perhaps drive out to somewhere a few miles away from town and bury in a wood etc

Without giving too much away what sort of ideas can you guys share?
