My sister in law had several old school maps that were going to be tossed. And they ended up at my house, still not sure how that happened. One cold afternoon the boys were driving me crazy and I threw the maps out on the floor with several permanent markers. Heaven!! We are allowed to mark on these? They questioned me, after reassuring them that they would not get into any trouble.. hours of bliss followed. They drew and scribbled all afternoon. It was great!! Who needs toys?
