I give a basin 1.5 days tops of glassing and then move to another one. In my opinion if you do not see deer within two morning and an evening glassing session you should probably move to the next basin. Plus you had three guys so find a place to glass where you can use three guys to your advantage and glass numerous basins at once. As far as the buck coming out in the same spot, that is hard to say. As long as a buck does not get pushed out he will hang out in the same area/ basin. That does not mean he will use the same meadow to feed every morning.
