Well, I bet no one has tried a hunt a wish they didnt cause its in the experience anyway. But it sounds like cost is a factor and if you can get a caribou or grizzly hunt for half the cost of a sheep hunt you can hunt the same terrain and still take home a nice trophy. Also, most outfitters have machines, horses or particular strips they use for less fit clients and can easily accomodate someone at 70 provided they can shoot straight!! The reason for the grueling hunts you read about are thats what the clients want or they are trying for the best possible trophy...
