There are a lot that antagonize me, the two that stand out :
A quality bulk elk, I have taken half a dozen, the largest a five point. BTW (before the wolves) I would pass on several decent bulls, small 6 pointers each year, and hope to take a cow during the late archery season. It just never came together on a really nice one. Now I am doing good to see half a dozen bulls, let alone a decent one, during the hunting season.
A quality mule deer. Took a 32" buck in the Frank Church Wilderness in Idaho with a rifle on the second day of my first ever deer hunt. I started big game hunting later than most at the age of 27. Talk about beginners luck, it was a solo, unguided hunt about 8 miles from the nearest road. Anyway, been trying to get one near that size with a bow for the last 29 years. The biggest down side of Montana, they just don't have the genetics for good mule deer.
