Just a hint. You should try and find a board member who lives in Southern California, especially around where the old citrus groves were in Ventura County. They used eucalyptus trees as windbreaks for the groves back in the day. There are several of those trees in Simi Valley. Or there were. Probably still a few here and there. There used to be some eucalyptus trees over in the Northridge area of the San Fernando Valley, too. A board member who lives near or in one of these places should be able to find those trees. They were planted in straight lines, side-by-side. Some are single trees, now, the rest having been cut down for development. But there should still be several in Simi Valley.
