Found the real deal...(it'll take me a month or two to realize it's 2013 now)...oddly the first graph I looked at does not look anything like the second one. I may be a newbie with NG, but I can read a graph! Here's the page I was on: if you select lower 48 states and hit graph you get a very different picture than if you hit "view history 1993 - 2012 (which goes to Dec 28,2012...I checked twice). One shows inventory NEVER going below 3000bbtu and one shows it dropping to around 1500bbtu for the same time period. How can this be? Things like this bother me...oops happy hour!
