Birds are gobbling early but not much in the middle of the day or later in the afternoon hours.They seem to be staying just inside the tree line or heavy cover until 6 or so in the evening. The Tom I shot was 50 yards deep in the woods where it was cooler. He gobbled his fool head off till I droped him at 6:45 or so. They do not seem as visible or vocal here in Southern Indiana but the harvest count is normal or maybe above average according to my check in station at Gun World in Corydon IN. As has been said I don't think any one factor can be used to gage what is controlling them this spring dogmatically. They are what they are and do what they do and we simply watch and come to conclusions which may not hold true year to year. Some things are set but not everything it seems to me.
