The mercury at Rapid City Regional Airport dipped to a record-breaking 11 degrees early Saturday morning.

The airport's coldest temperature record for Oct. 10 previously was 20 degrees, set in 1985. National Weather Service meteorologist Scott Rudge wouldn't rule out the possibility of Saturday's record low falling even further.

Without the ability to move freely around their "grocery store," Dueck said people would be forced to rely on goods that are shipped in, a prospect he termed as "frightfully expensive."

Mr Dueck: Throughout history, humans have been able to find food at a wide range of locations that don't "enjoy" thick year-round pack ice.
