Hi N.H.,
I live in Pa where our season just opened yesterday(May 1st).My first question would be,Have you located turkeys in or near that corn field?If not,did you find any turkey sign in or near that spot?such as,droppings,tracks,dusting areas,etc.
Rainy days are usually very good days to hunt turkey,as long as its not too heavy a rain.In Pa the turkeys usually head for a feeder plot or in general,an open field.Grassy fields are usually better than a freshly planted corn field.Feed is why.Food is plentiful in a field where there is grass insects and other tasty morsels.
Location is perhaps the most important thing in turkey hunting,and there is NEVER enough time to scout pre-season.Go to an area that you know has turkey,get there at lights first glow.Most times tom turkeys will gobble at almost anything while still in the roost.I like to use a crow call.I have never had much luck with owl calls for location,but some guys use them.Locating turkeys and being out in position before first light I believe are the most important things.There is alot to say about turkeys and turkey hunting and they never stop amazing me.I have been hunting turkeys here for 20 years now and I have alot of experiences too numerous to print here.The biggest problem I have is finding a longbeard that isnt with hens.If they are with hens you could be knight n hale and still wont call them to you.The hens will take that ole boy for a walk the opposite direction of YOU.I guess with that much said the rest may be a stab in the dark.Dont call too much if you locate a bird,and be PATIENT,that turkey has all day.GOOD LUCK :wink: Pa RR
