I didnt kill a whopper last year but harvested a meat buck (3xspike) in 62 last year on the last day.
I was hunting not far out of Montrose along the farm lands. I did see one nice 170+" 4x4 that I couldnt get a shot on and just couldnt close the deal on another 4x3. I passed on a very nice 3x3 a couple of different times. I could have harvested any old smallish to medium buck every day but was holding out for a really nice one untill the last day.
All in all, it was a very fun and action packed hunt. Finding big ones is tough in this unit unless you have inside info which it sounds like you have.
This was the first deer I have ever "dropped" in its tracks. Shot was 318 yards using the 150 ACCUBOND @ 2800 FPS.
