I know for around here......to see a deer that's 4.5 yrs or older is rare. The FIRST thing I noticed about my recent buck .....was how grey he looked (COMPARATIVELY). When you see fawns, yearlings and the occasional 2.5 yr old on a regular basis (actually....not that many 2.5yr olds in 2+ yrs hunting)......an "older" deer (more grey??) is somewhat more noticeable.

Like I said.....Duke's comment just got me thinking.......
