Mud mud and more mud

What is it about boys and mud? Our house is next to this giant field. A few weeks ago they came and bulldozed it and created a HUGE mud hole. So, every boy in this house is being magnetically pulled to it. Jeremy has had the Bronco in it, the F - 150 in it, J and T have had their little monster trucks in it. Its crazy. My washer is hating the extra loads of laundry though!!
