Open some beaver lure upwind, and they will come.

Do you mean that it isn't already legal to take beaver by any means? And what's this thing called a season?

But seriously, I hate when the legislature just hands off stuff like that to the DNR. Kind of a bad mix of legislative power, where it legally should be, being held and exercised by people ignorant of the actual topic handing off enforcement to appointees, who may or may not be actually qualified or political appointees, who pass it down to employees, govt ones, that actually do have college degrees, liberal ones, in wildlife. Then they turn around and ask us who are in the field daily to sit in on meetings for our "input" to decide something that was already decided in the legislature.

Back in my day, as a pipe-layer, I'd just saunter in to the local water hole and holler "Hey Baby", in a gravelly voice.
Worked sometimes. Didn't always bring in the most prime ones though...
