Good morning everyone -- once again I greet you from Montgomery County Community College in suburban Philadelphia.  Weather is nice and after my morning here I am off to the QVC outlet store to purchase Bob&#39;s Father&#39;s Day present --- get this-- he wants a manual push lawn mower for the spots he can&#39;t reach with the gas one.  They are on sale today for less than half the usual price --- a lucky coincidence.  Well I better stop writing a novel and try to get some work done.
