The cold week that we saw at the beginning of this month set quite a stunning record for US natural gas supplies, and put an exclamation point on our concerns about the natural gas that we're exporting.  In the first week of the new year, the demand for natural gas was so great that we had to use nearly eleven and a half percent of all the natural gas that was in storage in the US, in addition to everything that was produced by US wells during the week, to meet the needs of heating, industry, power generation, and exports.
