In early May (10 May 2007) I hiked to the site of the Aylmer Fire Tower Lookout in Banff Park. I was joined by some sheep, and, after the usual exchange of pleasantries, we agreed to do lunch. I ate the lunch I had brought with me, the sheep, however, preferred the offering supplied by the Park. Tiny green leaves are just starting to appear on this slope and were considered a great delicacy by the sheep. I suppose that after a winter of eating dried vegetation that you had to dig out of the snow something fresh and green would be a real taste treat.
