DNR has done random hunter surveys by mail over the years, using the mailing address info on file from license purchasers. I've actually gotten one or two of those surveys. They also provide the on-line input form when there's a significant issue up for consideration. The most recent one I recall participating in was the center-fire rifle issue. That was before our illustrious state legislature took over and over-rode the DNR's decision on that one. But they seem to take input from all-comers whether it is groups or individuals, and consider the various sources of input. I highly doubt they are naive about this in any way. You can bet though, that the various DNR powers-that-be have their own personal preferences on these issues, and those preferences will always be meaningful toward any final policy.
