I'll talk SLLLLOOOOOOWWWWW.
It doesn't matter WHAT THE WORKER SAYS, as far as giving permission to enter the CWMU to retrieve an elk.
The CWMU IS A DIFFERENT UNIT, than the Wasatch unit.
The "worker" should know the BOUNDARY lines, not the PROPERTY LINES.
That's why he's not pinched for TRESSPASSING. He's pinched for illegal take.
Boundary lines don't necessarily follow property lines.
Soooooooo, when you hire a guide to take you hunting ON THE WASATCH UNIT, he doesn't have a legal means to hunt a separate unit, in this case a CWMU.
Again, your knowledge of Texas doesn't apply on public land.
Just like no matter who WLH asked, the UNIT Waldrips ILLEGALLY TOOK A SHEEP ON, wasn't included in her UNIT(S) DESCRIPTION, so any verbal permission didn't change that.(Unless you take the director bear hunting).
A dude in NM can't give you permission to kill a deer in NM if you have a Texas tag. Easy way to think about it
