Season Three
HIDDEN WORLD
Turn the walks you already take into 15 curious investigations.
Find evidence of something that happened before you arrived. Go house hunting for a creature considerably smaller than you. Follow something wild with somewhere important to be. Find an objectively excellent stick.
No special trails. No mileage goals. Your neighborhood will do.
