Alberta or BC?
Well, I tried not to get involved in this debate, but someone seems to be pushing me in. So here's my 2 cents:
I hunted all over BC for more than 20 years, everywhere except the Peace (save a moose hunting trip in Buckinghorse), and I can honestly say that except for a fabulous Stone sheep hunt where we saw +-150 sheep in 8 days, that Alberta is far ahead of BC in quality and quantity of game (minor and major exceptions of course).
Bird Hunting: BC does not even rate - Pheasants, Hungarian Partridge, 4 types of grouse, and grain fed waterfowl the likes of which you cannot imagine if you are from BC. BC only wins in the Wild Turkey department.
Deer Hunting: If yearlings turn you on, then BC is awsome. For those who like a challenge (ie. more than 2 points), Alberta is unreal for both Whitetails and especially Mulies in the south (100% on draw).
Moose: Well, if you can get a draw, the moose are there for the taking in Alberta, from the Rockies all the way to Medicine Hat. BC is probably a little better in this regard.
No Antelope in BC. Almost no Goats in Alberta (once in a lifetime -not kidding- draw opportunity). No thinhorn sheep either.
Bighorn Sheep, well, I am planning on heading out in AB this year, so I'll let you know. But think about this; The Sheep season opens on August 25th and runs until October 25th (almost everywhere) the entire length of the Rockies! There are very few draws, and most of these are for hunting late season. I put in for sheep in BC for 20 years and never drew once!
The best thing about Alberta is the draw system - you build priority until you get drawn (or want to get drawn) and you can pretty much plan your hunting regarding draws before you even apply. No people with "reduced odds" getting drawn while you sit out another season, the 4th or 5th in a row.
Gotta run,
