Thanks to Mark D. for sending along this story:
NPR has posted an awesome look at drilling areas of natural gas. Linked to this map are some really interesting stories about natural gas and its potential. Note the smaller size of the Haynesville. Due to its organic content, the Haynesville discovery has the most gas of any of the shale finds in the country. Imagine if the Haynesville was the size of the Marcellus.
