Feet dog-tired this evening. Seems we covered every building within a five block radius. Lyle in the morning again, and me in the afternoon. I stayed out about six hours. Though neither of us turned up the needed component, I did not return empty handed.
Between us we now have enough foodstuffs to allow us to concentrate on the drone part the next couple of days.
While out I again saw the intruder. Judging by the time and space, we must be on its regular route. This fact should make it easier to track back to its lair.
So another reason to focus our efforts tomorrow. Perhaps we should go out together and not worry about the home base.
