Agree and disagree.
Ive called several elk to the roads (usually overgrown), and even called one across a clear cut 4 different times in one day (huge clearcut). All small bulls.
Any big or dominate bulls ive dealt with play with different cards.
I prefer to stay off roads, but if I have someone who's never shot a bull and don't care about size or where he shoots it at, game on.
Too each their own. When your singing the right song, and he's turning up the volume, i'd bet you could call one across I-5.
