Rob Mullen is walking the whole length of the northeastern state of Vermont and painting what he sees along the way. So far, Mullen has walked over 300 kilometers on the Long Trail, what Vermont calls America’s oldest long-distance path. Recently, he had only five kilometers to go before he could meet his wife and father for a break and supplies. It was raining, but he kept dry with his special clothing and equipment as he walked down the trail. The leaves on the trees were showing their autumn colors of orange and yellow. He carried walking sticks and a large blue bag on his back, inside his bag were his painting supplies. Mullen is a 64-year-old wildlife and wilderness artist. He is in the middle of hiking the Long Trail, which stretches 440 kilometers. The path runs from Vermont's border with Canada to the Massachusetts state line. During his trip Mullen has been making art, he paints the things he sees.
