I was first going to ask this in reference to your child getting into a mess while camping, but let's face it us adults can get pretty messy too!
We've been fortunate so far. The worst mess was when the kids started looking at the bait worms, and then playing with the worms, and then flinging the worms, and then flinging some mud and rolling in the mud.... Well, they had fun.
So what happened...and who started it?
