When the railroad was completed between Madison and Milwaukee in 1882, mucky soils in the glacial. swamp near Lake Mills made the tracks most unsteady. A bridge-tender stood guard, 24 hours-a-day, to warn oncoming trains of the danger ahead and caution them to slow their pace. One engineer chose not to head this warning and the locomotive lost control and tumbled off the bridge into the mud below. The train is said to be forever entombed deep in the muck along the present day Glacial Drumlin trail. We brew Down 'n Dirty Chocolate Oatmeal Stout think and black like the glacial muck.
