Oh I know. We used to fund our camping trips to Bennett by selling flys to Weaver's and Spring View. Back then it was Fur bugs, Celery flys, Light Cahill's, and Renegades.......and we (3 of us) tied many hundreds of them by lantern light on a picnic table.
All we really needed though was enough money to cover our campsite fees, some food, and enough gas to get back home.
We were Trout Bums before being a trout bum was a cool thing. 🙄
