On the "broomstick method", I have had trouble being confident that I had pinpointed the rearward end of the zygomatic arches, and so the earholes. The rearward end of the arches aren't visible from straight on. I've had more toruble with bulls than narrow faced cows, especially tuskless. With the bulls, it seems that the bulge of the the zygomatic arch below the eye seems to obscure the ends.

Any suggestions? I'm all ears, so to speak. And I'm heading out the 28th to try for a few more eles, both tuskless and one bull.
