We were on the narrows this weekend and our group found an Acuvue contact lens in the river near the take-out. It floated by and after a little chase we were able to slap it with a paddle and knock into the boat just before we missed taking out. Anyway, since we didn't find the owner at the take-out (waited and asked around for about two - three hours), we placed it on the railing next to the bench in a very easy to find spot. I'm sure it is still there since it has only been a couple days and i don't think anyone would be uncool enought to steal it. Good luck, hope it's still there.
