While exploring Reinaldo Ovando’s excellent site, I noted he has created a tutorial fly fishing channel. It has excellent information and the mayfly piece (Dean Hodson) was informative (note the typical position of tied emergers v. actual positioning. Perhaps the Klinkhammer posture is more for stillborns?). There are some exceptional South American sites with cutting edge technology to be found.  Vimeo has a free signup option and hit subscribe to Reinaldo’s site on the Vimeo link.Oh, Josko.Org isn’t bad either!
