Biggest Little Town in 3 Counties Traditional Cache

So the sign says.  That's right, the town of Sheldahl straddles two county lines so portions of it are in Story, Polk and Boone county.  This should be a quick P&G.  Bring your own pencil.  No room for tradeables, sorry kiddies.

From Wikipedia.  The area was settled by 120 Norwegian immigrants from Lisbon, Illinois on June 7, 1855; including Osmond and Anna Sheldahl and five of their children. It incorporated as a city on January 18, 1882.^[4]

The Chicago, Milwaukee, St. Paul and Pacific Railroad established a rail line through Sheldahl during the 1880s. In 2005, Union Pacific Railroad sold a 25-mile discontinued rail corridor—which included the line through Sheldahl—to the Iowa Natural Heritage Foundation, which enabled the construction of the recreational High Trestle Trail. Access to the trail, including a parking area and washroom, is located in Sheldahl.^[5]
