Events at Bonsall Park North By Error: Contact form not found. Desert Hockey Development (DHD) holds FREE ball hockey clinics for kids 4 to 14 years of age. We think ball hockey is a great way to learn the game of hockey without spending money on expensive hockey equipment. All you need is sneakers and a good attitude to play. The Arizona Coyotes and the City of Glendale generously assisted us getting our program off the ground. DHD tries to have introductory clinics every two weeks at the rink in Glendale, sometimes we even have free hot dogs and drinks after playing for a couple hours.
