Yes, sure. We have not socialized that issue among all our business unit, but let me start by business unit. In the propane side, we saw a bounce back last year. The law in the industry, Ron as you may know is that when you have a big increase in cost, you see more of a step function in conservation and then as people adjust to it, if you get a level environment, some of that demand comes back because people become accustomed to it, just like gasoline. You see a big drop initially and then people adjust and then they come back. It does not come back all the way, it comes back part of the way. So the propane business on a weather adjusted basis, I think our data in weather adjustments are not perfect which suggests that we had negative conservation last year that is we had some extra usage, a bounce back if you will. We always budget somewhere around three-quarters of a percent to a percent of structural conservation and so, we would expect over a period of time, it does not happen in linear basis, but over a period of time through new housings, through efficiency and appliances et cetera that your long term decline trends are structurally kind of one percentage. When you have a cost move like we had this year in propane, ordinarily, we would expect to see more with cost as Gene can do the math for you, but cost was at a buck last year at this time, now it is a buck fifty, a buck sixty, I do not know, somewhere in there, so that causes obviously customer behavior to modify. It is too early to tell how much that will affect us this year in terms of conservation if this reverses itself and then the next month or two, could prove to be an opportunity for us and the rest of the industry. I want to differentiate it though, I do not know if your question was directed to propane, but on the natural gas side, we really have not seen natural gas prices move a whole lot due to the supply storage conditions that are out there, so on the natural gas side, we would just expect to see our normal trend line. And regarding first fills, Gene, I think volume is doing okay.
