September is hopper season on many trout rivers throughout the country. There's nothing quite like a slow, deliberate rise... when that fish inspects, follows, and (hopefully) inhales that bobbing T-Bone. Some of my favorite patterns are big, gaudy foam bugs. Artificials, no doubt, but are they "flies" in the truest sense? We've talked a bit about this before, but since it is the foam hopper season, I think the topic is worth a revisit.
