Maybe a dumb question, but isn't there a relationship bewteen the propane and NG markets?  I know there is a relationship, but am unsure of what the outlook is on propane?
I believe they are only slightly related, in the same way oil and NG prices are related as energy sources.  Propane is a by product of oil refining, while natural gas is not.  The market for propane is well supplied as a result of the increasing use of oil.  At $1.10 per gallon, it may be one of the better energy deals...
