BLUE LAGOON MARGARITAS from Laura Price (really from Terry)

Recipes for Sam's Birthday Cookbook

Dear Sam, I am not really a very good cook but our good friend Terry is. She made these recipes for me when I visited her in her new home in Sonoma, California. After just one (1) of these Blue Margaritas, her husband Robert did a little "dancing" for me!
Very scary!! Ha ha!

Have a great birthday!!
Love, Laura
