Hi - don't worry! You're on the right page.
The Rossmoor Nature Association webpage got updated (actually a couple of years ago...where have you been!?!), and to make the address simpler, there is a shorter link. You can click here and bookmark the new page there, or you can right-click the link and Save Link, etc., etc., and so on. It's also possible that you will be re-directed to the new page, but no guarantee!
Please bookmark the new home page!
