Walking around Heisler Park, I usually see a plein air painter doing their thing. En plein air in French means "in open air". You can also describe this as peinture sur le motif , which means "painting on the ground". For more events and workshops in Laguna Beach, en plein air, go to LPAPA.org (Laguna Plein Air Painters Association).
