I've Ontario, but never been to Labrador, so I may be wrong on some things. But late August should be a good time for bears since I hunt them on early September in Wisconsin. I'm guessing you're hunting over bait. There is nothing I've gotten the chance to experience yet like sitting absolutely still and silent for hours and days and suddenly, silently, there is this beautiful, jet black creature that often seems to appear out of thin air. You thought you were still before the bear appeared, but now you don't even breathe for fear of scaring it away. It takes 2 or 3 eternities to decide if it's one you want to take, another to pray the bear into the right position and line up the shot. Remember to start breathing again. I probably will never have the money to hunt leopard, but I can only imagine it's similar.
We have a saying about bear hunting, sometimes you gets the bear, sometime the bear gets you.
Don't forget a thermacell!
Good luck and enjoy!
