I have 2 top five choices:

#1- A " Deer Slam"

1) Eastern Whitetail Deer(got this one 10 times over)
2) Mule Deer
3) Coues Whitetail deer(this one has skunked me for 4 years)
4) Columbia Blacktail deer
5) Sitka Blacktail Deer

I'm working on mine.
Just representative trophies, B&C not needed for me.

#2 - my "non-deer" goals

1) Mountain Goat
2) Caribou
3) Pronghorn (I finally got this one)

4) Moose
5) Musk Ox

This is my list - what's yours???
