When she offered extra credit to her students at East Ridge High School in Clermont to audition for last year's Lady of the Lakes Renaissance Faire, she thought it only fair to go first. Although her audition was meant as a how-to for her theater students, she got the part of a housekeeper. This year she's back -- as Lady Fiona, Duchess of Southwick, the mother of Lady Catherine, Lady of the Lakes -- in the third annual fair, which opens today at Hickory Point Recreational Facility on State Road 19 south of Tavares.
