RE: most challenging type of deer to hunt ?
The Whitetail and Couesare the same species.
As is the Blacktail and the Mule Deer.
Only seperated by subclass
Whitetail=odocoileus virginianus
Coues=odocoileus virginianus covesi
Mule Deer=odocoileus hemionus
Blacktail=odocoileus heminous columbianus
Proves that both the Whitetail andMule Deer are both masters of the enviroment.
I voted for Whitetail.
