Paul,
I hunt just north of Springfield and I've seen several bucks chasing does the last few days. Morning, noon, evening. First one was last Thurs evening. Saw two bucks dogging does that night. Yesterday I saw 4 bucks between 11 and 12:30 while at work. Two were right on does tails. The others on the same trail. I believe it's "game on" for the next few days.
