MY 2 cents here, contact the local game warden in there area, as well as a few of the local sporting goods stores(aka, gun shop/bow shops)
you many times get great info doing thing this, or I sure have!
if you stick to THERE web site and THERE references, you many times get one sided views IMO
another thing you can do is ask them for a list of all the hunters they had in the past 5 yrs or so
and contact a bunch ans ask them, make sure you ask for hunters that both tagged out and DIDN"T
this is MY suggestion for you/your buddy!
