"They" in question have no freakin clue buddy, whoever "They" may be.. I will give you one freebie seeing's how that river has no chance in hell in producing a pair of wild natal coho.. Going years back, and not anything recent, there was once a small push of lgr. than normal wild fish that would enter the system as late as the third week of dec.. Given the water conditions, which are usually favourable at that time of year, you would encounter a squirrel of a fish while targeting the first of the winter steelhead runs.. I have sat and watched guy's (right up to last season with the artificial fly regs. in place) kill a nickle bright steelhead, all the while thinking he got an odd coho late in the season.. Mother nature dictates when the last run occur's, take it from someone that has grown up his whole life fishing and studying such streams.. Twenty guy's can give you the answer your looking for and if they have the least bit of knowledge regarding the life cycle you may get within a certain hair of the answer.. I am sure you know which hair I am talking about..
Take your time when asking certain questions, especially on this board if you don't want to be eatin by the buzzards. One thing I have learned, listen to everything that is being said, and as much as you would like to throw your two cents in, hold back and pay attention.. You will learn more from listening than you will trying to b.s. your way through the majority of these threads..
This also goe's for the other newbie's that have entered this site.. Spend the 90% of the time that it takes to learn by what you hear and the other 10% in asking for help.. It comes down to, especially when guiding, knowing when to keep the yap shut and try to extract a bit of useful info out of something you may hear.. I have watched grown men cry in their pillow half way through a 4 month season because the b.s. their way into a position they could not make.. Listen do not beek!!!!whew-dirty
