On behalf of Friends and Neighbors of Washington Park I would like to let you know how much Dan Goldhamer’s presentation about the Japanese Beetle was appreciated on Feb. 8 at our monthly meeting, and how much we learned. I felt like I was back in a senior biology lecture in college. His presentation style was relaxed yet professional and all questions and comments were carefully answered. The attendance at the meeting was our largest ever, over 50 people, literally “standing room only”. Dan was also kind enough to refer us to the JB fact sheet on your website, so we were able to post the link on our website. We will keep Dan’s name in mind for further presentations.
