RE: Enough time?
Your kiddin right? I go after work all the time when I only have anywhere from 15 minutes to 1.5 hrs to hunt. If I have less than an hour I sit on the edge of fields rather than go into the woods and disturb things to much. You should have done your scouting so you will know where the deer normally enter the fields you will be hunting. If your hunting woods I wouldn't go too far in, just to where you have seen deer feed in the afternoon. I shot a 125" 11 pt back in 2000 on opening day of ML season in the last minute of legal shooting light. Total time in the stand... 5 minutes.
This time of year, it pays to be in the stand for as many minutes aspossible.
