Gregg,

Thanks to the feedback and sharing your experience. That was very helpful! Those are along the lines that I was thinking, but it is nice to get some first hand experience and knowledge.

I had not heard the theory about the barometric pressure. That seems plausible along with the internal instincts telling them that it's time to slow down and rest. I believe I will follow your lead and let them rest. If they want to feed soon, then so be it. If not, then they will get cooled down a little early.

Thanks for sharing...
Jonathan
