Four of us are planning a self guided archery caribou hunt for the fall of 2013. This will be our first hunting trip to AK, I would like to know how strong the heard in 19C or D is, I would also like some information on the type of cover available. I have looked at topo maps of these units and 19C looks to be rather rough terrain, I belive if these units are worth hunting 19D would be the better of the two. Any how I would apreciate any insight you all may be able to provide.
