You're right!!!

We have also started taking FRS radios with us when we go hiking/camping. One for each member. The rule is simple, when one or more leaves the camp (gathering firewood, etc) we all turn on our radios.

We used call signs (Wolf, Coyote, & Sandman) since that tripped my 9 year old nephew's "trigger". It also insured that he remembered to turn on his radio when called for.
