I don't know squat about how saving veggie juice in a vacuum bottle will work but your observation about homes back in the woods is interesting. If the problems occur in warm times, the leaves will prevent scavengers from seeing the house but in winter there will be no leaves to obscure the view. Removing the mailbox is a good thought and obscuring the driveway is also good. However if there is a drainpipe in the ditch at the driveway, that's going to be a problem. My plan, if things get dangerous, is to make sure someone armed is always in my woods next to the house to protect the property. Radio communication from the woods to the house is also obvious.
