All it takes is one crumb to stir up some seagulls.

That’s what happened just at dusk on the edge of the Sea Bright beach the other day as people were packing it in and up at the end of the beach day.

It was no Alfred Hitchcock movie, but the skies were eerie hues of blue and yellow peppered with the gulls.

Yes, there’s a gull in every beach crowd … and photo.
