Ben’s father, an american history teacher, had a thirst for knowledge to rival abraham lincoln’s. under his guidance, the family had traveled last year from their home in michigan across the upper midwest, with a final destination of mount rushmore in south dakota. their trailer became a private passenger train complete with a dining car and restroom. no longer stuck in one place, this home on wheels provided for all his family’s needs while moving them from one unusual spot to the next. they could camp out while still being at home, and the scenery changed almost every day. the trailer stopped in small cities and towns across the states as if it were a train. like a midwest lewis and clark expedition, ben and his family explored wisconsin’s waterfalls, explored the many untouched, untamed forests of the upper peninsula of michigan, and sighted the occasional bear, elk, and other wild forest animals. they remained in one place long enough to get tired of it and then moved on to the next stop on their trailer-train ride to their final destination of mount rushmore, where they’d all marveled at the sheer size of the magnificent monument. ben looked forward to discovering which route they would take and which unique places they might visit this year.
