We did really well last year in October - Thanksgiving weekend, in fact - fishing for Coho in the tidelines off Secretary. Tons of exciting action, and we had our possession limit in two days. Of course, this has been a particularly dry year, so who knows? Keeps it interesting...
My wife (who does 90% of the driving when we fish) maintains our success with Coho is due to her habit of zig-zagging across the tidelines, rather than parallel to them. Since most of our strikes happen just after the boat crosses the line, I think she may be on to something.
