Here in Nebraska, it's been in the mid to upper 70's also. It's supposed to get a little bit cooler this weekend....64 on Saturday and 58 on Sunday. I have found, at least the last few days, that they are out here until at least 8:30, then come back out at 5:15 or so. Talk about your dawn and dusk hunting. I saw a huge buck this morning. I can only hope that I see him this weekend.
