Solar in Arizona - 1999 Solar Potluck Photos The 18th Annual Tucson Solar Potluck was held on May 8, 1999, at Catalina State Park. Some of the homemade solar cookers were larger than their owners. Solar cookers were used throughout the day to prepare small food items to be given away as samples to curious onlookers. Cupcakes were baked in this solar cooker and then given away as samples.   Go to: Tour of Potluck - Page Two   Return to: Solar in Arizona Page
