National Geographic's 2014 Adventurers of the Year made a stop in Hastings May 2 as they journey 1,750 miles by bicycle from Ely, Minnesota to Washington D.C.

Dave and Amy Freeman are pedaling to the country's capital as a campaign to save the boundary waters. They will stop in a number of cities along the way to promote their book, A Year in the Wilderness, and ask supporters sign a canoe they have in tow as a petition to stop copper mining that would threaten the Boundary Waters Canoe Area watershed.

"It's a national treasure that belongs to all of us," Dave said.

Dave and Amy spent a year in the BWCA sharing their experience through video, photos and blogs. The pair did not flip a light switch or step into a building for an entire year. Their new book tells the deeper story of their adventure.

Dave and Amy's main goal is to educate others about the boundary waters. The BWCA is a popular wilderness destination and Dave said the proposed copper mining could damage or pollute the water.
