Here in the Twin Cities, it's at the Holiday stations. The "Blue Planet Gas" is a product of Flint Hills Resources refinery at Pine Bend. Most of the feedstock is from Canada. Privately held company, owned by the Koch family, very conservative, with libertarian influences. F.A. von Hayek's books in the company library!
Boom and bust is the name of the game in commodities.
Everyone keeps saying that has changed because of the demand from China and India but I am not so sure.
Oil can still go higher just because it is priced in falling US dollars which China (and Japan) hold a lot of.
People can invest in Canadian oil & gas company stock through owning NA energy and resource mutual funds.
Suncor, Encana, Enbridge and of course, Exxon and Shell, are all in the Alberta fields.
But in the market, pigs get slaughtered and these mutual funds are way up and to make a profit one has to take a profit, i.e., sell.
On the other hand, IMO, there is always one really good reason to invest in NA energy funds and that is, energy independence from the ME and OPEC would be a bargain at almost any price.
