Every Day in May—EDM #106 Something tart or sour

Day 6 of the Every Day in May challenge—something tart or sour. Lots of lemon and lime trees in my parents garden here in Northern California. So it just seemed natural and so right to spend time outside in this perfect sunny warm weather sketching and painting on the patio for the Day 6 challenge.

Back to gray rainy 55° Maine tomorrow...
