Ozarks hardest part of trip for one cross-country cyclist

17 year old Abby Smith cycled 4200 miles across the country this summer. According to Abby:
By far, the hardest part of the trip was riding through the Ozarks in Missouri. Before the trip started I was dreading the Rockies because of the elevations we would be reaching. In the Rockies, though, we climbed very gradually for days. The Ozarks were a bunch of short, steep, ups and downs. The ups were so steep that even in our lowest gears we felt like we couldn't push any harder. Those days were filled with frustration, but we all managed to get each other through it.
