Williams is the author of twelve travel and outdoors books and is a recognized expert on trout fishing, flyfishing and travel around the world. His popular book, So Many Fish, So Little Time (Harper Collins, 2007) has been one of the best-selling fishing books the last few years and has received numerous rave reviews and awards.Williams and McPhail have learned what works in teaching students over the years and have built a teaching philosophy, and not just for beginners. In flyfishing, a flyfisher never quits learning--a new know, a new cast, a new strategy. They both teach people from all walks of life, in the classroom and on the water. They tag-teach anglers at seminars at boat and flyfishing shows, at lectures at local flyshops and fishing clubs, at book signings / slide shows at national chain bookstores and at private guiding lessons on rivers or lakes. The authors reside in Amarillo, Texas.
Mark D. Williams and W. Chad McPhail have also coauthored Colorado Flyfishing: Where to Eat, Sleep, Fish and So You Want to Flyfish, and each is the author of other books on fishing, camping, and the American West. They both live in Amarillo, Texas.
