its not about how far, its how close! but, i dont shoot over 40 yards on average

I have to agree with most here...Alot depends on the energy of your set up, alot of KE is lost after 30 yds or so, think you might have to be shooting 70+ # for a shot at 60 yds. Keep in mind that the reaction time of a whitetail can be as fast as 600FPS for its initial reaction. My bow isnt shooting quite that fast!
Take a shot which you are sure will provide a kill and recovery, if you let this one go, another will cross your path sooner or later.

Practice I shoot up to 40 yards usually. Shooting a deer I am confident up to 30 yards.

i am extremely comfortable out to 35...however, this last saturday i arrowed a doe at 46 yards...my furthest shot with a bow to date

I recently learned that a distant cousin arrowed a deer at 60 yards. I initially called BS (not so bluntly), but his mom swears that he has witnesses.
60 yards seems tough to me. Not tough in the respect of your arrow going where you were aiming, but in the respect of the deer still being there when the arrow arrives. If they can jump/duck a shot at 20 yards they should be able to hop-scotch around the arrow at 60.
I have never needed to shoot outside of 25 yet, but tell myself that if a perfect situation presented itself, I'd go 40 MAX!

I hunt in the woods, so the longest shot I ever see is with in 30 yards.

I wouldnt quite go so far as to say hopskotch lol. The probability of the deer hearing the bow at 60 yards is highly unlikely if its a modern compound... I took one at 49 this year. The deer stayed feeding head down as the arrow was in flight.

I hunt in the woods too. Thick woods. In fact, I NEVER hunt by or around any fields. My first shot of the year was at 49... The woods is so thick in fact, that I couldnt get the damn fourwheeler in there and I had to drag her out on the trail I came in on 200 yards through the briars seemed like an eternity lol.

Jeez, I can't even see the target at 60 yards! lol.

200 yards through briars IS an eternity.
