Yes, I know it is August, but August on the coast can be chilly! Once it warms up around noon, you forget you even were chilly in the morning.
I now have a park date basket in the trunk of the car. In my basket I have reusable plates, cloth napkins, water for washing, utensils, soap, and a washcloth. The camp chairs also seem to have moved into the vehicle.
Park dates with good friends are great and are only made better when those good friends bring you home grown veggies!
