My family went on a roadtrip this weekend and brought a small basket of toys and games to entertain ourselves. In fact, this is the set of goodies we picked. In order to not leave a single wind-up monkey or treasured truck behind, I took a photo of our loot with my phone as we were unpacking.
RookieDad Alec used this photo at the end of our trip to repack everything. Depending on the age or interest level of your children, you can use the picture as a scavenger hunt game with them.
