I love a light rain or snow(if it's happening at 60 degrees). No seriously, you face the same decision when you take an evening stand.

Will the deer show early enough to track tonight? Will my shot be good enough to find him with the remaining light? If I can't find him tonight will I have time tomorrow? and on and on.

Bottom line shooting a deer carries responsibilities and everyone must be man/and or women enough to live up to them.

Good luck!
