May have been getting tired during the last hour, but saw three dim satellites and nine jets.  About 3:45 am CDST I heard a snort to the South and saw three bucks silhouetted against the sky glow of Ames and Des Moines.  One was young and had small antlers, one had a middle sized rack and one had the biggest rack I have ever seen on a live White-tailed deer.
