The problem I had was carrying my Canon DSLR in pack since it weighs so much but I learned a valuable lesson on last elk hunt. I left it in tent since I thought it is too heavy for today's long trek that was planned. ARGHHH! I had elk 50 yards from me but more importantly, we had what I still believe was a wolf that stayed with us for a 1/4 mile, laid down and watched us eat lunch, walked across a deadfall over a small drainage cut and then laid down again licking his paws about 50 yards form us just sitting eating lunch. Can you even imagine the photos that I would have IF I had my Canon with me? NEVER AGAIN! It will be in pack no matter what! I can see him walking across that deadfall in my mind as clear as a bell but try to show that image to someone! What a photo op that was lost!
