The trees are growing. If they can mask the lower parts of the climbing frames, the whole aspect will look a lot better.
It is sooooo spectacular!!! How high is the fence? It seems not very high, Is there any hot wire on the top of it?
The wooden part of the fence you can see is probably 4 or 5 feet high (1.2 - 1.5 metres) then there is another 2 or 3 feet of normal fencing then 4 or 5 feet of smooth plastic that curves inwards as it gets to the top. Unless they carry a set of bolt-cutters or a dremmel I cant see anything getting out of there in a hurry baboon. ( I never noticed any "hot wires on it at all")
