Actual Reading @ Laurel Today

Gas 7495 or 8 ccf per day during a very cold spell, since Duke on Feb. 18 read the following:
Gas 7388 as of 1:55 pm February 18, 2008.
So this means Laurel used 117 ccf since the actual reading I took January 31st, through Feb. 18, or 6+ccf per day during a cold spell.
