Mark Weir has started a WTB program called the Dirt Apprentice. What is that you ask? Well, it teaches kids how to build trails sustainably while simultaneously getting them outside and away from their devices. Here are some photos from the first go at it. Way to go Mark for helping future generations have an appreciation for the outdoors.
Gus Weir always has the best snacks.
The kids completed a 100 yard section of trail and learned about erosion and how to make sustainable trails for the future.
