Double and triple check that all of your equipment is in the truck and in working order...Batteries flashlight, rangefinder.....
Opening morning here I went out and forgot my rangefinder. Had a doe come out first thing in the morning estimated her for 30 yds and she was only 20.....Gave here a harmless haircut off of her back....The bad thing about it was this was the FIRST time I have ever ran a video. Here is my blunder..
