Radio message from Dad

From Torg Adventure

Now that Dad's gone, you're the man of the house, er, bomb shelter. You take over his duties, including monitoring the radio. The main radio is a powerful HAM base station in the shelter -- the antenna is hidden in the woods behind the house. Dad took a handheld transceiver with him. He also went over the codes he invented for this trip with you before he left.

Your dad sends a message every hour as he walks to the meeting point. At the end of every message, he says, 'The geese are flying south' to indicate that everything is okay. You never reply, your father worried that someone would triangulate on your signal and find you.
