CORONA DEL MAR – George and Sharlee McNamee have enjoyed the cool ocean breeze, soothing waves and swaying palm trees from their sandy, oceanfront back yard for 27 years. A sign on their shed reads "Just another day in paradise." But their bliss has become frustration. The California Coastal Commission wants the McNamees to remove the barbecue, restroom, shower, canopy, cabinets and concrete picnic tables from the couple's back yard, which is immediately behind Corona del Mar State Beach. Their property line extends into the sand near Inspiration Point.
