The IOS has its 25th anniversary in 2017, and a superb way to celebrate it will be to get yourself to the Czech Republic in July where, during Oak Open Days based at his arboretum near Poděbrady, enthusiastic and dynamic IOS member Dušan Plaček is sponsoring a "Birthday Banquet" for participants at Poděbrady Castle.
