to give you a little update....called the guy and asked him if he has done anything to the grass over the years. he said, "Oh, i was watching an infomercial years (10) ago and purchased these plugs to thicken my lawn". i started to laugh. I told him, "exactly. the plugs are not viable in michigan"... so, i am quoting him a new lawn for the front of the house. will let you know hot it goes. you guys are the best. another potential sale due to Lawnsite!!
