Two friends in Tuscon have had Simon Crawford help train their dogs. One told me last year that he informed his clients last year not to come, as the Mearns population was way, way down. Seemed honest in that regard, as the Mearns have been at a low the past 2 seasons. We did have an OK monsoon this summer, so hopefully they rebounded some. I have never met Simon, so cannot vouch for him personally.
