Adventures of Johnny Tundra, Cold-Weather Engineer: 'Plugging a Government Leak'

July 20, 2016
There is a leak at the highest reaches of the Montana state government—the kind not associated with a loose-lipped staffer, but, rather, a safety relief valve on a 40-year-old boiler. The supervisor of facilities maintenance and operations, Hank Hoovestahl, wishes the environmental guys who decided to connect the steam boiler to a newer hydronic boiler would have talked to the O&M staff first. Luckily for Hank, he does not have to ask his pal Johnny Tundra twice for help.
