Dear John, I agree with you! Now with the Green movements rise in political and other matters, they have insisted that some of the top Colleges and Universities help out the Parks who are on a limited budget. For instance Crystal Palace Park had a children's zoo, but it was deemed too expensive and was closed down. So one of the Green MP's told Capel Manor a very famous college of Agriculture, if you want your budget then reopen the Park zoo as a farm so the children of London can see what a farm looks like. They have done a good job of it, and many schools now visit the farm in the Park as it is called on a regular basis. Dulwich Park has help from lots of Colleges and other places and have set up wildlife areas, and all sorts of things for the children to learn about!
Also at Crystal Palace you can go on a Horticulture course learning all about how to grow and plant things at all levels, this is a good idea as it involves Parents and their children!
Regards.
Neil.
