There are a lot of interesting places beyond rigid classification scheme of Google Maps, therefore adding new items could bring new dimensions to Google Maps and to made it much more attractive and much more meaningful for local people. For example, in my small town of Protvino I added mark for oldest tree in the town.
Age of this tree could be estimated as 200 years. Also interesting that this pine clearle visible on first satellite image of Protvino made by satellite Corona in 1971.
