Tip: customized honk or whistle for locating lost children, etc.
I just thought I would share a story that might help someone. Yesterday I was downtown enjoying lunch with a friend and my daughter and several of her friends. After lunch, the girls started walking towards what they thought was the direction of their parked car. They got lost downtown. I jumped in my car and drove around looking for them, but couldn't locate them. Then I began honking our special customized honk. While Mary and her friends were trying to find me, she said " I hear my Mom". Her friends couldn't understand, but Mary knew exactly where to go to find me. Our customized honk saved the day.
You can make up your own customized honk. Mine was simply left over from my high school years. The honk went to the rhythm of a cheer: "Rangers, Rangers, we are the Rangers." I use it for school pick ups, football game pick ups, etc. I practice it on the kids if I'm waiting in the driveway just so they know the honk and will respond to it when necessary.
This same method could be used with a whistle or other noisemaker when not in the car. Great way to find kids in an amusement park I would think.
