So much for calling for help.

People can wave signal flags at sensible intervals to repeat messages.

So much for calling for help.

1) Native American smoke signals ((smoke they got--big time!))

2) messages by drums as Pacific Islanders

3) cup your hands beside your mouth and yell for help

4) move to a civilized part of the US without a Uni-party Dem-Socialist government that destroys civilization wherever found. Leave your Dem politics behind with your other garbage, please.

They should pay some older American Indians to teach classes on how to send smoke signals.
