If I ever had a "List" I'm pretty sure it has been more than filled. I've been so fortunate to have had the opportunities I have enjoyed.
At an early age, I wanted to hunt our local Saskatchewan Canadian game - all our waterfowl, small game and both whitetail and mule deer. Check. Then my ambitions evolved to black bears and moose, game that required an expedition and considerable wilderness skills. Check. Then I got an addiction to elk hunting. That has continued for thirty more years, successful every year but last. Pronghorn Antelope competed my quest for available species of local game. Check.
Somewhere in-between, I needed to hunt our Western/Northern mountain game. Backpack and horseback hunts for Yukon and British Columbia Dall sheep, Goats, mountain Caribou. Check. (Except that the goats and the mountains that they live in beat me every time, despite a valiant effort on several hunts)
Then my attention turned to Germany. Wild boar, and Roe deer. Check.
And then Africa. I suppose Buffalo were always on the "list" and If I think about it some more, Kudu and Warthog were "must haves". Check. But I never in my wildest dreams expected to hunt bull Elephant, Giraffe, Gemsbok, Eland, or several other worthy critters in Africa. So those were just bonus experiences and cherished for their special combination of circumstance, and opportunity.
I still have never hunted barren-ground Caribou in Canada, so that's happening in September.
After that, my plans revolve more around sharing with family and friends the "how to" I've gained from that 50-some years of wonderful experiences than adding to any personal lists.
