This man is traveling 300 miles by wheelchair to push for more accessible nature trails

Ian Mackay considers himself a cyclist and a birder -- a nature buff who gets lost on lush trails near his Washington state home for hours every day. But if popular opinion had its way, many people wouldn't expect Mackay to be able to pursue this passion. They may even assume he couldn't truly enjoy the outdoors independently. That's because his "cycle" is his power wheelchair, and Mackay is a quadriplegic man. Using a power wheelchair in nature does have its challenges, and Mackay is the first to admit that.
