Why use an analogic slide rule in this technological age? The same reason we love tool watches - there's nothing quite like getting our hands dirty. In pre-digital 20th century, the circular slide rule was utilized to execute simple to semi-complex calculations, which you can now achieve on-the-go. So adventurers; divide your time, subtract your excuses, add sturdy gear, calculate risks, and multiply your outdoor escape with the Expedition Enigmath.The Black Forest, or Schwarzwald, is a mountainous region in southwestern Germany known for its scenic highlands and forest landscapes overlooking serene tourist-friendly cottage towns. But its true mystery lies deep in the woods, where the outside world disappears and a calm, hushed ambiance envelopes the watcher. These forests are said to have inspired the Grimms Fairy Tales. The bountiful supply of wood spurred local builders to craft one-of-a-kind timbered houses, special cuckoo clocks found nowhere else on Earth, and of course, the burning of pine wood for Black Forest Smoked Ham. That, followed by a slice of Black Forest cake after a long day in the woods, is adventure done right.
