Behind the scenes with the production crew

The miners' futures are on the line at Porcupine Creek. After 80 days, the miners are behind schedule, and the Hoffmans have run out of money and deliver the crew an ultimatum: find $10,000 worth of gold in the next two days, or the families have to head home to Oregon.
