wow you are definately putting some time into it. i think what you are doing is good, but try not to visit an area to often and spook the birds out.

as far as them answering locatoar calls, i've heard birds gobble at 3am and during rifle deer season in november. if somethings gets their attention nd they want to gobble they usually do.

i don't know about your turkey population but i dont but anywhere near as much effort into scouting as you do. PA does have an abundant turky population tho. when i do get out, i usually just go turkeu hunting without the gun. i walk around using turkey calls to get gobbles. if i feel a gobbler is coming in i just sit and shut up to maybe get a view of what he looks like. if i dont scout an area, i just show up before the crack of dawn, listen for a gobble, and chase after it when i hear one.

your methods sound good too tho
