Update

       As we went to bed last night we were counting up our drying machines.  We have 4 ceiling fans running, 4 floor fans, and 3 dehumidifiers!  It sounds like a tornado in our basement!  But the carpet is drying nicely.  There does not appear to be much, if any, staining.  The jury is still out on the possibility of  replacing the bedroom carpet since it is not yet completely dry, but we are feeling very thankful when we consider the major disaster that has been avoided!  The weather forecast is for at least 1/2 inch of rain and then 2-3 inches of slush tonight!
