It's a PGC stated fact that only 40% of hunters return report cards. Could it be that the number of report cards sent in reflect the true number of deer kills?

After all, we've been told by the PGC that Pennsylvania has 1.6 million deer. We all know that's not true. How do we know that the 40% figure (whatever that is) isn't the real number of deer taken?

I think George Venesky (former Commissioner) once asked to see and count the return cards and the agency was very hesitant.
