Fairbanks News Miner, by Matt Buxton.  With less than three weeks before voters decide the fate of an oil tax system the industry has spent millions to defend, ExxonMobil invited a group of reporters to visit North Slope’s Point Thomson gas field.  Reporters from the Fairbanks Daily News-Miner and Anchorage-based media outlets took an ExxonMobil flight on Thursday to tour what is said to be one of the busiest places of development on the North Slope.
