If it's any consolation or perspective...I've been fortunate to be on 7-8 flyout AK caribou hunts over the past 15 years; although I've been fortunate to harvest a caribou on almost every trip, it has never been easy. Some hunts we saw several hundred caribou over the course of a 6-7 day hunt; but on some occasions we saw less than 50 caribou in 6 days. Their movement does seem to be impacted by the weather, and they are above all an unpredictable animal. Kudos to you and your guys for doing everything that you could, and sharing the hunt with us in detail.
