The three-headed Christmas tree

There is a three-headed Christmas tree in Mount Royal. It is enormous, maybe 4 or 5 times my height. Really, there are 3 huge fir trees that grow so close together that their branches and needles intertwine, almost obscuring their three trunks. Christmas lights wind around their joint lower girth, making mega-circles. At the top of the trees, there are spirals of light for each conical head.
