I went onto their Facebook page this morning to thank them for allowing access to see the goose, and saw a recent Facebook posting of theirs in which they announced a tour of the facility on Saturday March 11th. Now, obviously with this rain that tour was very likely get canceled or rescheduled, but it looks like it's worth paying attention to their Facebook page to see when they would reschedule it. This was a general tour for the public, not specifically for birders but sounds like a good opportunity. They also have tours like this of other facilities that are usually closed to the public.
