Often it is hard to tell if the last arrow will keep the animal down. If you think that it is mortally wounded it is a good idea to sit there and wait for it to die. If for some reason the deerdid get up. You would have had an idea where it went. Experience alone will tell you when to wait, and when to approach. If you appraoch too soon, and thesecond arrow was not a good onethere is a chance that it could get up an run.

With that said, congrats and welcome to the club!!!!!!!
