Whatever else you do in town, book a tour with Mark Jones and this operation. When a guide grows up in the area, studies a location's history, writes books about it, is passionate about it, and loves to talk about it, you have a recipe for a fantastic tour. We could have done another few hours with Mark. Engaging, practical, informative, funny, self-deprecating, and just so excited to keep telling us, "how cool is that." Man, what a great time. Thanks, Mark.
