How old?

[ReflexHunter]

Here is a pic of a buck i got this year on my Stealthcam when it was overlooking a scrape during the rut here in Central WI.  The land has lots of farming broken up by woods here and there.  I have a pretty good idea of how old he is but tell me what you think. (I think I have a pic of this guy from last year as well, I will post that pic after I hear some estimates).
