Ma’am, dismount that manatee. Fifty-three-year-old Florida woman Ana Gloria Garcia Gutierrez was arrested Saturday for hopping aboard one of the sea cows protected by Florida law. The second-degree misdemeanor could cost her $500 or 60 days in jail. Gutierrez stepped forward after realizing she was the woman caught astride a manatee in photos released by the Pinellas County sheriff. She said she was new to the area and didn’t know playing cowgirl with the creatures was a no-no. Police arrested Gutierrez at Sears in St. Petersburg, where she works.
