Pine Air: The second “Plein Air in the Pine Air” opportunity is Thursday, Oct. 17 at 9:30 a.m. at Double Trouble State Park in Berkeley. Artists should bring their own materials and easels. After meeting at the visitor’s center, spread out and paint the various sites on this reconstructed cranberry farming village. As this is an eco-minded group, no dumping of solvents or paint water is allowed. Bring containers to accommodate this and take out any trash you create.
