No April Fools here. Those are real motorcycles in a real tree, and I saw it with my own eyes (which are also real). The story goes that a bunch of bikers would get together for a yearly celebration of some sort, and would always burn a bike. Then, they threw the burned-out skeleton into this tree, which neighbors our maple-syrup making friends. After several years of this ritual, the tree ended up looking like this.
I just thought it was cool.
