ive never ever blown a locator in the morning. i go into my predetermined listening spots and listen. if they aint talkin on their own they surely aint coming to a hen call. that IS why they gobble anyways. then when they start sounding off i pick one. usually the first gobble, closest gobble, or the one gobbling the most...usually the same bird...at that time its dark enough to sneak in fairly close and setup without getting busted.
i wouldnt wanna wake them up early...they could become irritable
