Pat Caffrey, Dining Services Director, demonstrates his ice carving skills for a local preschool. The 300 pound block was carved in 30 minutes with a chain saw. Pat has been sculpting ice for 30 years, and has completed over 1000 carvings. This marks the 17th year the school has invited him to teach their students about this form of art. The ice is manufactured in Tucson with purified water to make it crystal clear.
