First off, an elk isn't a deer, neither are moose and caribou, but they are all cervids.

I haven't hunted anything besides Whitetail yet, butI hope I can soon.
Just can't afford to pay a fortune for an elk hunt.

Of the animals above that I haven't hunted but I would love too, and are my favorite on the list, I choose the elk.

Also, when you said Sika, did you mean Sitka? Because Sitka deer are a type of Blacktail. Maybe Sika is a type of exotic.
