I hunt just south of you just east of Longmont. We were out Fri. afternoon and it was about the worst hunt I think I have ever had. We were on a frozen lake too and we set up for the afternoon flight. The only problem was that there never was an afternoon flight. We never saw one bird the whole afternoon. Not a one. Not in the air, not in fields, we never saw a thing. I don't know if they had moved out of the area or if they just staying the fields all night eatting. It was just a very depressing hunt. Glad to hear you did well though. We just havn't seen that many around.
