This is our youngest, Brandon.  It had rained overnight, and this large puddle was left by the side of the road.  Brandon found it after breakfast and was entertained for over two hours.  He had toys in it, sticks in it, threw rocks into it.  Had this been a typical vacation, he could not have done this, as we would have needed to move onto the next activity.  However, we are into relaxing vacations.  This was one of our camp days, in which we stay at the campground all day and let the kids do what they want to do.  He wanted to play in the puddle.  Who needs TV?  This is truly cheap entertainment.  He did, however, have to be hosed off when he came out.  The mud part of mud puddle was quite accurate.
