Sometime this month, the 1,364,835th visitor to the Sleeping Bear Dunes National Lakeshore in 2012 will arrive at the Dune Climb, hike to Pyramid Point, or perhaps bike the Heritage Trail and enjoy its stunning autumnal beauty. In doing so, that visitor will officially make this the busiest year ever for the Glen Arbor region, the most profitable for local businesses, and perhaps the most hectic one too.
