"The jist of it was, that that this guy fished the Allenberry C&R section with a 6wt and bass poppers. Everyone else was fishing tiny midge patterns. They'd be holding their breath as the trout would drift under the fly. Along comes our hero. He'd splat a size 4 popper down and a trout would explode all over the thing."
Almost the same thing happened to me! 20 years ago, before I became a 100% fly fisherman, I fished the Allenberry C&R right below Allenberry, not downstream by the wood bridge and I had a UL spin rod with 2lb mono and tiny roostertails. I waded all over the place and didn't catch anything. I put on a small Rapala, 1 1/4" floater/shallow diver and still didn't catch anything. Then I cut the plastic lip off to make it a tiny top water plug and almost every cast the trout would explode on it!! After a half dozen trout, a big one broke my 2lb test (then I was too stupid to use a Uni knot) and I didn't have any more top water plugs.
Now that I go back there often, I always take some panfish poppers and some foam body drakes....... or foam hoppers.
Even on opening day, a big dry will catch fish when the tiny nymphs won't get a hit!
That's the wonder of flyfishing! Some of my best trips were catching trout, a couple days after opening day with a size 10 "Royal Coachman"....... now that fly goes back a long time! I'll bet most on here don't tie it anymore!!
