One call for deer and once call for elk for me. I also answered questions for my son about deer.
It's ridiculous that they call once for each species, especially when it is months later as was the case for elk for me this year (I don't hunt the shoulder season). I know the reason they call for different species has to do with their sampling method. Basically its not random if you call the same people for each species. That said it is still ridiculous, they don't get accurate results, everybody lies, and even those that don't lie just don't remember when it is up to 6 months later.
Mandatory reporting would fix all of it. Simple and efficient using today's technology.
