Draw a treasure map of your block.
Create a family "adventure song" that you can sing together as you walk through the park.
Write out a list of secret ingredients for a magic potion (3 twigs, 1 acorn, 2 rocks that look like cats) that you can search for along the way.
After a winter of being cooped up, there is no limit to the fun we can have with a simple walk around the block. Stretch your legs AND your storytelling skills!
