My son was watching a field full of deer last Saturday evening and he did see a little bit of bumping going on, but nothing dramatic and nothing that lasted any length of time. That is not to say though that you could not see a hot doe in a given location at this time. But I think the "meat" of the rut is still 1-2 weeks away.
One way you can know when things are really cooking is that the does are less likely to be feeding contentedly out in the open because the bucks will just not let them be when things are really hot. As of right now, I am still seeing plenty of relaxed does out in the fields.
Every year there are plenty of people that think there is an early rut because they see a buck bumping a doe "early". But not every doe in the woods is ready on the exact same date every year, there is a bell curve distribution of sorts. Some, a few, may be ready now, but most, as in A LOT of them, are coming up in the next 6-15 days or so.
