jmontesfusco, you did the right thing by waiting to track. You should know that quartering to shots are always like playing Russian roulette. I cannot say that I have never made a bad shot but, I have learned to wait for a good shot or let the animal pass. About five or six years ago I lost about a 140" deer to a shoulder hit. It was not a bad shot angle, just bad shot placement (pre-range finder days). However I only got about four or five inches of penetration so I am confident the critter lived. Like yourself, I did not take up the trail until the next morning. I can honestly say I have not lost an animal since. I learned that if you give the deer time it will most likely present a great shot opportunity. Good luck finding your doe and good luck sleeping tonight.
Bucks and does alike, if I ever lose the rush leading up to and after a kill, I will hang it up. Knowing me, that will never happen.
