Could be. My family already has predetermined code words or phrases that tell members where the meet up point or final destination is. This is so messages can be left without telling everyone. It’s also so that certain family that are in positions that get advanced notice can warn rest of us without appearing to.
Technically we already live in the hills, but have alternates if staying home isn’t possible. One 5 acre plot we bought for back taxes about 1.5 hrs away. Sister and brother out of state.
