One afternoon, while picnicking and enjoying a marshmallow roast with our daughters and grandchildren, we watched a very young porcupine ambling about just inside the wooded area next to our table. The sight of two young boys running toward him drove the little fella up a tree, where he perched safely, just about 10 feet from the ground. He stayed there - apparently undaunted by the attention - for as along as we hung out enjoying the sight of him.
The video I've included here is from one of my encounters with a porcupine at Frazer Point. I really did get this close!
