The key.

Newcastle, Gateshead Winter Festival. Enchanted parks.
My husband and I went with our daughter and grandson to visit Saltwell Park at 6pm.
Saltwell Park is an enchanted place. By daylight it is an ordinary park, but at night, when the last lingering visitors have been ushered from the gates by the familiar figure of the Park Keeper, extraordinary changes take place, and they did. There was magic everywhere.
This is our grandson turning the key in the tree, to make it talk.
