We added a pair of walkie talkies to our urban gear packs. Now we can keep in touch when we go on bug hunts and nature walks. We’re never more than a couple meters away from each other when we’re hiking, but walkie talkies are just cool. I looked up police ten-code, so we use that when we’re chatting.
Here we are using our squawk boxes. Our apartment is across the street from where I teach, so I called over to say hi.
