The numbers have been counted, and the Sleeping Bear Dunes National Lakeshore reports that the pristine National Park in northwest-lower Michigan attracted 1,531,560 visitors in 2012 — a record-breaking tally by a wide margin. On the strength of the “Good Morning America” television show’s “Most Beautiful Place in America” honor in August 2011, and the added attention it cast on Glen Arbor and the surrounding region, 13.59 percent more tourists ran up our dunes, hiked our trails and frequented our restaurants and galleries last year compared with 2011.
