I live pretty close to Taber, something like 45 minutes away. I'm just south of Lethbridge about 20 minutes. I never really hear anything big being shot around there. Manyberries is mostly antelope, and Cypress hills has elk, moose, and muledeer, but im not to sure about the whitetail.
I know where I am, WMU 108, theres a couple nice ones shot every year. I've shot a 151" 5/8 7x5 two years ago, Someone shot a 156" last year, and my friend shot a 163" this year...Picture below...I also shot mine this year, and it'll probaly score 120ish, i'll get some pictures tomorrow.
