I was just about to report back that Bone Field was a bust too. I was there from about 7-10 on Monday and heard just a handful of shots on the other side of the field. What time were you out there? Spoke to the TWRA agent for a quick second Monday morning and he said there weren't any birds there Saturday either.
I may be interested in trying the Williamsport field when it opens up on the 15th. There's sunflowers planted there. I'm not a huge dove hunter but I'm thinkin if I were a dove I'd prefer a sunflower seed over any other seed.
