Although the Sitka Blacktail is a smaller cousin to the Mule Deer, they are extremely abundant in Southeast Alaska. Their weight ranges from 60 to 250 pounds, and they have exceptionally keen hearing and sense of smell. If you are in fairly good physical condition, you may want to consider the early season hunt, which will take you above the tree line, up where the larger bucks roam. This is one of the most scenic hunts that you'll find in Alaska. This extra cost covers the chartered floatplane costs.
Open terrain makes it easier to see the deer.
More deer to see. Less chance of a wounded animal to escape. The lakes are more remote and you'll find the hunting is even better than the beach access hunts. Cons - Cost. I can't think of too many other reasons not to.
