This was our canyon pond, which produced limits of ducks all season. The farmer said that it had never frozen over. In one night of 8 degrees and no wind, it did, and stayed that way for about a week. Really a bummer. Here's a pose at the "mallard tree" with two other guides, Mitch Trammell (my son in law) and Mathew Rosenbalm, an apprentice guide, after the last hunt of the season there.
