Guys we already do something like that for a club I belong to. It's the group that gets the depredation permit hunts (and no I haven't been on one, yet). We have to pass the bowhunter's education course....pass a background check....and pass a "proficiency" test (which is administered at 20 yds).
Criteria is on the paperwork presented to municipalities/businesses/etc...that are seeking the aid of the group.
That sounds good but what I am speaking of would be on a "grander" scale, not just on the local level.
