Unfortunately the only reason there was only 4 of us there is because it's passed prime time on the Cap. It can get super busy in mid October all over the river including that spot. I think the Cap probably have only 1/2 of as many people as in Mid October right now.
You're totally right! This time of year the coho are darken up but you do get the odd clean one the entered late. Most people will think they have a bright fish till the bonk it. If I'm out to fish the Cap it's purely C&R but still practising proper fish handling methods.
