In the quiet moments before Solemn Oath Brewery's second annual "Oath Day" kicked off yesterday, I noticed some new artwork on the back wall. "What's that about?" I asked co-founder John Barley. "That's our growth mural," he explained. "It's a wolf being grabbed by the ears. And if you can imagine what it's like grabbing a wolf by the ears, you know you better not fucking let go."
