40kms, LOL I drive farther than that to get to the grocery store. Put this into perspective. They are comparing Linc's find to the Alberta Oil Sands, in fact it is potentially larger. Have any of you ever been to the oil sands?? Take a run up to Fort Mac and you will quickly understand that 40km is compareable to a light human gas release in a 50 knot wind. (you can't say f--t in here)
