One late summer evening, I took the kids to the park right after a rain storm. They were full of energy and I wanted to wear them out before bedtime. When we arrived, I saw that there were a lot of puddles in their favorite spots. Normally, I would've insisted they avoided them (the mess, etc.) but that afternoon I let them have at it and boy did they have fun! It was worth the extra laundry and cleaning. We'll definitely look for more mud puddles in the future!
