Where can a gut get good reference photos including measurements to help in field judging?

Henry,

Same as on the goats posting, maybe someone else knows of such a website, but I sure don't.

The best thing that I have used is some of the late Duncan Gilchrist's videos. You can see what is available and might be of interest to you at: http://www.wildramhunters.net/catalog/index.php?cPath=30

I would personnally suggest both ADVANCED FIELD JUDGING NORTH AMERICAN WILD RAMS and FIELD EVALUATING THE THINHORN RAM.
