Interesting that the letter just says head. The lady who did ours last year was a temp. sub from Wisconsin because (she said) CPW couldn't staff enough with the training to cut them out.
This is super interesting that the CPW won't accept hunter-submitted lymph nodes. Is that really what folks are hearing from the bios and wardens on the ground?
In Wyoming, I've personally submitted 4 different CWD samples that I have pulled lymph nodes off myself this year - 2 deer I killed, an elk a buddy killed, and a deer another buddy killed. This is not user-friendly if they want to get the data down in Eastern California and probably worth bringing up to the powers that be and any orgs that have pull down there, like CBA.
Odd though, CPW has a video out to show hunters how to remove the lymph nodes.I can see from a scientific standpoint why they would want to collect the data themselves to verify accuracy in reporting.
