We were on a short visit from Ontario, Canada and arranged for a half day of birding with Carl. He was very receptive to my email requests for a specific day and target species. He picked the two of us up promptly at the planned time, and provided extra binoculars, water and snacks. He also brought along a scope which came in handy. His knowledge is top-notch, and he clearly enjoys guiding. Overall a terrific experience!
