Wasn't that Trini Lopez who made the song famous back in the days of folk singers and simpler times? If you remember Trini, check the obituary columns to be sure you are not mentioned - LOL! But seriously, folks... If you are here in Southern California and don't have a lemon tree, that must mean your nearby neighbors do. Because one tree usually supplies enough lemons for everybody on the block. That means every seafood dinner, every pitcher of fresh lemonade, every apple pie [the juice keeps the apples from turning brown] and every martini with a twist for the entire block.
