When we played Highlands a couple of years ago up there I walked over and checked out the cannon. The crew said they had just taken over for a crew that had operated for years and were happy to tell us all about it. They seemed very knowledgeable about it and knew what they were doing. It is a very cool civil war replica fireing black powder. When they fire it, it really rocks the house. This must have been a freak accident. I don't think they should get rid of the cannon maybe take extra precautions or something. You accept risk every time you get in a car, or airplane, or a kid suites up. I certainly hope he recovers soon and he is able to live a good life with his injury.
