I think its a bad year in general. Because of the late spring, the berries in the woods were turning ripe just as season opened...in our area it was the mushrooms. They will eat natural food first...add that on top of the heat and it lowers your chances dramatically.
I PM'd you about another thing you can try wilcam, I wished we lived closer I could just sit you in one of my stands. I've just been baiting them to keep the coons around so I can trap them next month, they are still getting nailed, and I know there is at least 2 bears that are over 300. this picture is from when I baited yesterday.
