Well Rob, if I'm anywhere within 30 miles of Philly, it's about 95/5 NG/LP. If I get out into the more rural areas, it swings to about 80/20 NG/LP. If I get about one hr. from Philly, it's all LP. Of course, we have a LOT of oil heat here, too.
We have a little more than one million around Philly :-)
