It's just like the green drake hatch on Henry's Fork, except that you have to soak in a vat of penicillin afterwards.

"I prefer to fish the dingleberry hatch in the poop chute section of the river. I tie my dingleberry flies on a size 4 short shank, wide gape hook."

Received the above recently from Miles via email.

Professional decorum prevents me from listing the actual materials for a dingleberry fly. Trust me, you don't want to know.
