Buddy of mine went with a few people about 4-5 years ago to hunt bison north of Fort McMurray. The used every means of transportation available to get where they needed to go; truck, boat, atv, foot. He hunted on a trap line with the owner who knew where the bison were, so he had no problem finding one to shoot. He told me it was a tough bugger to drop. It took 6 shots from a .30-06 and 3 shots from .308 to take it down. It took them 2 full days of work cutting the meat up and preparing it for transport out of the bush. It took them another day and a half to get home with all that meat. He said it was one of the most tiring weeks of his life. He was glad he did it, but now sure if he would do it again.
