We just bought some walkie-talkies. The kids are having a blast with them. They're going for lots of walks... "Can you hear me now?" And when the older ones went to the store yesterday, they took a radio with them, so we could call them. It was great! "Did you want us to get some milk?"

We got the radios on sale for $28 (half off). They can get expensive, but if you shop around, you can get good radios for not too much money.
