After February 2007 the usages are not normal because the house was vacant for much of the time. But February, 2007 is ok because Genny was living in the house. So February 2007 usage is ok to compare with February up at Laurel for 2007 and in comparing for February 2008 at Laurel. (Previously we "established" that the two houses used about the same -- before we "super-insulated" Laurel in the fall of 2007)
