At a northern WI registration station that I help at during the regular gun deer season, they registered about 400 deer during the t-zone hunt. A DNR staff of 5 was collecting samples for CWD testing. Samples were marked on a grid map of the county so too many samples didn't come from a specific area, but from accross the county. Only quality samples were collected, no head or neck shot deer and no fawns. Approximately 120 samples were collected. FWIW.
