My "learning experience" was a case of being a little hard headed.

I fished it one Labor Day and dry flies were working great. Also other normal flies worked too. It seemed any dry would work for me if I threw it along the reeds.

Next year I fished it 4th of July and started out with the "usual suspects".. leeches, damsels, drys, etc... and only landed two fish in two days of fishing it.

I put that down to brookies being moody and the bite being off.

Met this one guy up ther I'd talked to the year before and he said.. nope.. they're biting like crazy.

Turned out they wanted a tiny little #22 parachute to match the tiny chronies hatching. I thought the tiny chronies were just "noise" and the fish would want bigger flies.

That's my learning experience.
