DD practices at our local elementary school field. The school district will not be rushing to fill in the hole DD digs when she practices pitching with me. She has dug a respectable hole at this point. I won't be able to drag out a rake to the field. I figured we kick some of the infield dirt (which seems to have a decent clay content) and add some water when we are done for the day, that might help. Anything else we could do, or is there a particular order of adding water and kicking in the dirt that would be best?
