i usually roost them the evening before.....i get there fairly early, at least 2-3 hours, i sit and i watch .....i do this prior to season as well, then the next morning i will try to get me a location on them, after awhile, i can get some kind idea of all of the roosting areas they like...during the hunts, i basically do the same, the night before i see them go in, i know where approximately where they will be if they don't gobble.......i haven't been able to get a gobble out of an evening bird but maybe one time, not from the lack of trying...they just dont like gobblin in the evening for me i guess, lol.....maybe thats why i spend so much time in the woods, if i could go in , hear a gobble that evening, i'd be set.....but that never happens to me....
