If only I was referring to the Salvelinus confluentus. All the same, I won a pair of Costa del Mar shades from Trout's Fly Fishing fly shop in Denver. They do a weekly "Name that River" contest on Facebook, typically for a $25 gift certificate or a fly line. But as luck would have it, the week I knew the river, it was a $150 pair of Costas - and they fit perfect. They even sent it Fedex Ground to my house, which was probably another $10 or $12. Bully for me - and thanks to Trout's!
