Wow, first off you deer is not lost!!! forget hunting . find your deer!!! in the Day light. go to the fence crossing where you last saw it and follow any trail , look for any blood. it has been my experiance that a deer hit a little hi can run a 100 yards with out a drop of blood showing up. do a grid search but look for blood She is not far from that fence. if there is water close by she is probably real close to that. don't be so quick to give up.
