In the area I hunt during the extended they are really call shy. I've only tried a few times with cow calls but the results were so bad I gave it up. They just hightailed it out of the area. I've seen guys across a canyon just blowing away on their bugles with no results. (actually I didn't wait around all that long to find out so who knows)
That's not to say they wont bugle because if you hit it right they will, as I learned last year. They bulls were bugling really good one morning and I wanted to try a cow call, but I decied not to risk it. I got lucky and and it worked out with my first bull.
I dont necessarily leave the call at home, but rarely use it.
