I was hiking with wife and daughter in Cape Breton, Nova Scotia, in the summer of 2001. On one shortish hike (Skyline trail) we saw pilot whales out at sea to begin, and a momma moose and her calf munching in the woods. Big animals! It was magical. Hiking back I tripped and fell. Figured it was a tree root. A little later I did the same, and saw no roots. This was my first expression of "foot drop" related to fatigue. After two courses of physical therapy, and much of 2002 chasing a diagnosis, I found one, like most, through a process of elimination. I had MS. Major bummer. Still is.
