How old do you think this guy is...3 years???

Sway back, I would guess older,5 1/2 or maybe6 1/2. Looks like an old deer to me.

hell of a nice lawn mower

Gotta love our mountain states, no need for fake deer for lawn decorations. My buddies wife actually put up a fake buck in their yard a couple years back, a real buck came in and thrashed it. Some areas put up fences to keep wildlife in, we have to put them up to keep wildlife out (they love to eat your garden, and if they find a weakness in your fence they seem to let all their buddies know).

Looks old to me. I think I see a beard on it. lol

That has got to be a pretty old deer. sway back, pot bellied, grey haired. I better stop I am starting to sound like my wife!

like everyone else said, sway back normally means older more mature deer

the better question is how big is the one behind the tree?
