"Here deer, deer, deer, deer, deer."
"Bammmmmbi, Bammmmmmmmmmmbiiiiiii"
What has worked best for me in the past is:
Setting up and getting into/out my stand. (Had two deer watch me for a good 20 minutes from about 25 yards a few years ago as I set up a ladder stand.)
Snoring
Going to the bathroom (gun/bow must be a least 15ft away) works real good. There is a correlation to the more "complicated the maneuver" the more/larger deer you will see. The sound of a zipper coming down and an extremely full bladder draws them in like moths to a flame.
Having the shotgun slung on my shoulder while walking to/from the stand works also. I think that as I walk down the trail, the deer are putting on a 1950's style big budget musical and jumping/dancing/backflipping across the trail behind me like Fred Astaire and Ginger Rogers.
Eating Lunch/taking a drink. Had a small buck skid to stop about 10 feet from me while I ate lunch on a fallen log. Of course my unloaded shotgun was about 5 feet away, and I only had an "anterless only" tag. (used my antlered tag the day before). That face-off lasted about 3 minutes, before he decided to use a different game trail to complete his journey. But it was fun to watch as I remained motionless and he snorted, pawed the ground and bobbed his head up and down. He knew I didn't belong there, but couldn't figure out what I was. (for the record, I was wearing BDU camo pants, an orange bird hunting vest over a plain green sweater, shooting glasses and an well worn orange NRA Staff Youth Shooting Sports Camp hat.)
I've used calls, scents, rattled antlers, and pretty much used/done everything else and in between. The deer are gonna do what the heck the deer are gonna do, especially once they all go into freak-out mode when all the hunters start stomping all over the woods and fields. IMHO, Carrying a four leaf clover is just as good as buying all the latest and greatest gear and tech-no-doodads advertised on the hunting shows. Go out, be safe and have fun in the woods and fields. Remember: "The work starts when the hammer falls."
