My last big game hunt would be to the extreme NE part of Saskatchewan. After a long drive to Points North landing, we'd take a single otter float plane to a river system that I know of, with my two sons and maybe another like minded person. A couple canoes and a wall tent, and wood heater, Last week of September.
I'd take my Krieghoff drilling, 16x16/7x57R and an ugly but reliable Ruger canoe paddle stainless M77 in 30-06. We'd hunt moose by calling, black bear by glassing & stalking the berry patches, and cast for lake trout and huge pike and flyfish for grayling in the mid - day periods. For variety we'd take the drilling and hunt spruce grouse and ptarmigan, and maybe pot a few ducks.
I figure a week of that would be a good way to put a grand finale on a hunting career. But I actually plan to do it a couple of times before the end.
