Doug if you are in woods where turkeys are this time of year,provided they don't have hens with them,they should answer or come in to your call.
If you find a Gobbler alone and he answers,don't call to much,if he answered,he knows where you are and sometimes will walk in to your setup without anymore gobble'n.
Set up to call with your back to a big tree faceing in the direction you think the turkey will come. Also try to set up,where the turkey is in range when you first see him. (ie rolling land,curve in road,bench on mountain side) If he can see where you are calling from he is unlikely to come in (ie across an open field,open hard woods etc.)
If you really like Turkey Hunting get a subscription to Turkey and Turkey Hunting Magazine,lots of info in it. They are on the web,do a search ,there are a lot of back issure articles that have a lot if infomation.
Hope this helps
Good Luck ,hope you get a big one.
