Buck from a distance

I took off work early to get some hunting in.  Whew it was hot!  I almost didn't go but did.  I went to the club and wanted to sit at 5 (the road between the fields and first place I got a deer a the club).  I sweat my ass off on my way into the stand but it was a nice, comfortable sit.  I was facing the field so that, where I expected to see deer would be to my right.  At approximately 5, I saw a (what a think was a) 4 pointer at the rock wall.  It fed for a bit and then wanted to get out in a hurry.  Did it see me?  did it smell me?  Not sure.  The only other thing I saw was a guy with a power hang glider...that was pretty cool.
