Oil boom and a kidnapping alter Montana town - Article Photos 3/8

This Feb. 28, 2012 photo shows a truck driving by the welcome sign for Sidney, Mont. Sidney is experiencing a boom spurred by companies seeking to extract oil from the massive Bakken formation beneath western North Dakota and eastern Montana. More than 16 million barrels of crude are now being pumped every month from the massive Bakken oil field beneath eastern Montana. But Sidney's new-found prosperity doesn't dull the sting of the recent kidnapping and apparent murder of a local teacher, Sherry Arnold, who authorities allege was snatched from a Sidney street by two men among the thousands in search of their own slice of the boom's multi-billion-dollar payoff.
