It seems that some of the other changes have already been included in this map (see the education centre, the new path on the field down the hill from the enclosure, the new greenhouse above, etc.)
It would be nice to see this enhanced. I don't quite understand the new fencing though. Will they split the animals into two areas? Will the new walk though fence be lower so as to make it more like a petting zoo than a high security prison for the animals?
