Saturday was Ancient Technology Day at Pueblo Grande Museum. There were all kinds of demonstrations such as basket weaving, stone tool making, jewelry making and other ancient technologies. Above is the "chuck wagon" and the gentleman here was demonstrating a baking technique making cinnamon rolls inside dutch oven. He's just lifted the lid that is filled with hot charcoal to see how they are cooking.
The back of the chuck wagon was filled with all the essentials to whip up a tasty meal on the road.
