I live in Alaska and I hate this practice too. This has been voted on over and over and each time it was banned but then the administration always finds a way around it, over-ruling and over-turning the vote of the people. Sounds like its up for another vote pretty soon.
Did the state ever try a relocation program or some other humane way to control the wolf population? I read that the people of Alaska vote the aeriel hunting program down but it keeps getting through. The wolf makes a comeback and now we are killing them. Sad........
