My wife and I are considering a trip to Alaska this summer. We would obviously like to go to Denali if we take the trip. We are both 27 and avid National Park fans. The thing that is concerning for us in Denali is the recommendation to hike in groups LARGER than 2 people due to the wildlife etc. We would be coming there just the two of us so we wouldn't be able to satisfy this suggestion between the two of us. Does anything have any advice/workaround on this problem? Should we be concerned about this?
