I use these steps

1 get permission to hunt the feild ,some farmers frown on walking through standing corn
2 camo that matches the corn ,I use a marsh grass / catail patern
3 you need wind ,10 mph or faster ,to cover your sounds I have hunted in 40 mph gusts
4 find a feild that borders a creek or wood lot ,big is not bad
5 slowly ,I mean SLOWLY work into or cross wind ,if you think you are going slow enough slow down ,I walk cross feild cutting from row to row looking both ways before moveing to the next . The deer that I see ,if I do it right are beded between rows , mostly looking down wind. I work back and forth along the first 200 yards along a woods ,work acrost move 50 -100 ft go back each pass will take me 20 min or so
If you spook a deer and you will don't sweat it ,I have never seen deer leave the feild, it just moves a 100 yards or so. Come back in a few hours
feild hunting is a late morn. to mid after noon hunt like 10 - 3 or so
Shots are close 6 feet - 10 yds .I shoot 4 blade muzzey 115 gr heads . fixed blades are best I have shot through corn leaves most times ,I wear a back quiver less to catch in the stalks. shots maynot be broad side ( rarely will be) so good peneration is a must ,cut on contact heads are good, lots of shots will be 3/4 away . I use a different bow for this than my stand hunting.
This type of deer hunting is tough on the nerves and takes persistanc but the first time that you can kick a beded deer it is all worth it
