The elk I have on camera doesn't have any ear tags or markings either. The other 2 pictures I haven't posted are 35mm and day time and much better quality showing both sides. I'm pretty sure it is the the same elk as the one posted by jumpumndumpum, at least it sure looks very similar.
A 5x5 in dallas/madison area isn't too far off from me either. Haven't checked my cameras since the last pic I got on 8-20, maybe he's still hanging around /forum/images/%%GRAEMLIN_URL%%/grin.gif
