Every once in awhile, I read something really inspirational that makes me see the real potential of society. After learning about the Berg brother's bike ride from Anchorage, Alaska, to Patagonia in Argentina, to raise money to build a house for the Lake Agassiz Chapter of Habitat for Humanity, I knew it was one of those times.

Since August 11, 2011, Nathan Berg, 24, Isaiah Berg, 22, and David Berg, 19, have been cycling over the Pan-American Highway, living on $10 a day by buying donuts on sale and covering then in peanut butter. The boys are aiming to raise $60,000, enough to build one house for a person in need. Their goal is to cross the border of Mexico by late November and make it to Argentina by May.

While this particular ride was inspired by the boys' sense of adventure, they are being fueled by their desire to help others. They also aim to document a trek full of beautiful and moving landscapes as well as off-the-beaten path travel. The kindness of strangers has also helped them along the way, including an inspired group of elementary school children from their home state of North Dakota writing them letters, people offering a place to sleep, or being given a generous meal.

So, what sets this charity ride apart from the others? On their Bound South Facebook Page, the boys write:

"Many charity rides spend a great deal on various amenities and promotional efforts. We wanted something different. Bound South is a rugged journey of reflection, a fully self-supported trek across some of the most inhospitable places in the Americas. Supporting our cause allows you to become a part of our story. Every dollar you donate will go directly to Habitat for Humanity to build a home."
