The gang invited grandpa to hunt moose. They headed east into the rain which dissipated by nightfall. Next morning they built a campfire near the tent and cooked warmed vegetable beef stew. Grandpa gave a bull grunt, followed at fifteen minute intervals by two others. An hour elapsed before grandpa gave the "I have a headache" cow call. Within a short time the ten-year-old grandson proclaimed, "There’s a bull."
