A “solar oven picnic” is scheduled for this Sunday morning and early afternoon in Riverside Park.

From Solar Cookers International:

Most solar cookers work on basic principles: sunlight is converted to heat energy that is retained for cooking. Sunlight is the “fuel.” A solar cooker needs an outdoor spot that is sunny for several hours and protected from strong wind, and where food will be safe.

From FaceBook event page:

Cook and share food using only solar ovens at the top of the grassy slope in Oregon Hill’s Riverside Park. If it rains or it is too overcast the event will be postponed.

Seeing as the forecast is partly cloudy, this may have a 50% chance of happening, but as with the recent neighborhood yard sale, this event is an experiment that will hopefully improve with re-iteration.
