I think they're still hungry, but you might have to "match the hatch" more closely. They might be in a different area than what they were earlier this year. Either that, or they've been caught enough so they wised up on you. If you really want to catch some, and artificals just aren't doing it, try live bait, either small BG or GSH.
It's good to hear that the Anderson Fry worked for you.
