That's a good sign to me. Every year I have a great opener on the first day, it seems like the season bluntly put, sucks.
This season, on the first day I heard, and saw, NOTHING. The next several days have been very productive.
Just saying. Keep your gun ready, and make the most of the time spent in the woods. It only takes a few more minutes for things to change!!
God Bless,
