I had seen the presentation by Simmons and came to your same conclusions.

However, something has happened in the last 2 weeks with back month NG prices

All winter and spring, when front month 2006 prices were crashing from $15 to under $6 due to incredibly mild winter, the back month stuff stayed very tight on all time highs - it has plummeted in recent weeks while front month has rallied a skootch.  This is consistent across months starting in 2007. So there is definitely another side to this story - some big players chose last 2 weeks to have confidence in nat gas being more plentiful in 2008, 2009, 2010 than they previously had.

I am contrary enough to believe that they are wrong.  I was very happy to snap up October 2009 natural gas for a bargain price.  Others think the same, the contract rallied on Friday.

IMO, North America is one long hot summer or one colder than average winter away from a real gas crisis.  The LNG imports will not be ready in time to avert this.

The big issue to me is that natural gas must be, "not too hot, not too cold, but juuust right...."

If the natural gas price is too high, it destroys demand in the U.S. as people will try to "fuel switch" to electricity from cheaper coal even if that means more CO2 release (logic:  I don't have to pay the "full price" of global warming, but I sure have to pay the full price, and NOW, to heat my home), and as companies "outsource" to places in the world with cheaper natural gas, and damage employment in the process.

But, if the natural gas price goes too low, the pipelines and LNG projects cannot possibly be done at a profit.  This means that, as one other poster said, "one bad winter" could be catastrophic, because the lead time needed to have the gas pipeline and LNG plants up and providing gas is years.  By the time we realized we needed the gas, we could not possibly build the infrastrure fast enough (go to TOD UK and look at exactly this situation in Britain) to save the U.S. from a very serious (and in New England/upper midwest states, a possibly deadly) supply problem.  The LNG and Alaska gas pipeline are two perfect examples of projects that even thier backers admit must have a "sustainably high" price for natural gas to find investors/backing.

Right now, though, the price is bearish, as back to back to back to back mild winter/summer/winter/summer has led to an astounding amount of spare gas  (and propane likewise, the great under utilized fuel is easily stored and in the summer, cheap and in surplus).

The best thing we could do is try to build faciliteis to store even more gas and propane, so that when we have these mild spells, we have somewhere to save the fuel for a rainy day!

Not sure Propane is that easy to store: yes it liquifies under moderate pressure at ambient temperatures, but in large quantities that's an expensive tank relative to unpressurized tanks for liquid fuels, or cavern storage of LNG.  

OTOH, storing a moderate amount of propane as a liquid in a pressurized tank in a vehicle seems to me as a better way to go than pressurized (but still gaseous) methane.  Why is that not done as often?  Perhaps because methane has a price advantage over gasoline, while propane does not.

Talking about price, from what I've read, a large part of the propane supply (in the USA) is as a byproduct of the refining of oil, which may explain why its price is unlinked from that of NG, and tracks oil fairly well, despite NG "liquids" being the other source of much propane.  As usual, the price is determined by the marginal, most expensive, source.

Oops, I meant "cavern storage of NG", not LNG of course.  LNG isn't stored any longer than necessary for transport, as the energy cost of keeping it cold is enormous.
