Yes, I hunted w/Winterhawk archery Sept. 06. I had a fabulous time. Wasn't successful, but when I left I was so satisfied I didn't care. Of course a Elk been nice, but only been a bonus. I'm going back this Sept. all booked & set. I can tell you anything you want to know. Feel free to personally e-mail me w/any questions.
Far as the wks. 1st wk you risk warm temps, and chance of the Bulls not being in full rut. But you also get first crack of the season at them. 4th wk should be in full rut, and get to experience all that action & bugling. But you risk colder, and possible snow. When I booked in 06' I was faced with the same decision for wks, and chose the 4th. The weather was up & down on us, and got some snow. So made it tough. So its a guessing game.
