I agree with what the other guys on here say... just be patient. Make sure you also control your breathing,, even though you may not "hear it" the deer may hear you loud and clear. Also remember that it's best to draw back your bow when a deer is behind a tree, brush, or something that can block your movement. Deer do not have depth perseption.. that's why they are so spooky,,, they don't know how close you really are. That's always why sometimes they stand there 10 yds away and stare at you for 10 minutes.
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
