You know how you get all fired up about those sulphurs that come off on your local stream? Maybe you're super-jazzed about some late-evening caddis hatch at the river. Or perhaps you're the newbie in the fly shop spouting off about the epic Adams hatch you just fished. You think those are hatches? They're not hatches. This is a hatch that's so intense, the police have to get involved. Shot in Iowa during a shad fly pop-off.
