The National Maritime Museum, Royal Observatory and Queen's House are situated in its grounds. The park was originally owned by the Abbey of St. Peter at Ghent. In 1427 its ownership reverted to the crown, and Henry VI gave the park to his uncle, the Duke of Gloucester. With a stunning view of Canary Wharf and the Isle of Dogs, and a rich history within its 183 acres, there is plenty to explore within Greenwich Park.

Our January program is privileged to have Kristen Tregar as our speaker. Ms. Tregar is the co-author with John de Lancie (the actor who portrayed the character Q on Star Trek next generation) of a radio play depicting the events surrounding the Kitzmiller v. Dover Area School District trial. The trial decided the issue of some of the Dover school district board members attempting to insert creationism disguised as "intelligent design" into the 9th grade biology curriculum. She will discuss the trial and the process of writing the play. (Bob Leonhard has seen the play and it is riveting and tense). Ms. Tregar's bio is below: Kristen Tregar is a dramaturg, director, playwright, and theatre teacher. She earned her Ph.D. in Drama and Theatre from the UC San Diego and UC Irvine joint program. In addition, she has a MS in Forensic Science from City University of New York- John Jay College of Criminal Justice and a MA in Educational Theatre from New York University- Steinhardt School of Culture, Education, and Human Development. In 2013, in collaboration with Irish colleagues, she founded *The Ireland Project*, an intercontinental devised theatre work with high school students in New York and Tallaght, Ireland. Her original short story "Far From Here" was recently published in *Stay Awhile Longer: More Scenes From Temecula Valley*. She has two rescued dogs (Kira and Harry) and she rides, competes, and foxhunts with her horses, Andromache and Baker Street Irregular. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid.
