Went out to my local pond yesterday. Weather was partly sunny, in the 50's. A slight breeze from the west to the east.

Saw all kinds of activity, the bluegills were hitting something in the surface. I didn't see anything flying above the surface - midges or anything.

Started with some small surface flys with no luck. Went to some small PT and other assorted nymphs with no luck. The bluegills were hitting all around my offerings.

As a last resort, broke out the gurglers and the crappie candy, still with no luck.

What do you think they were hitting on. I could hear the "popping" noise from them hitting something.
