I'll be in Portland for a meeting during the first week of November. I have a few days to spare and want to fish some famous Oregon waters. I was thinking of spending a day on each of the Sandy, Deschutes, and North Umpqua before heading back to California. Are these good choices that time of year, or should I consider other rivers (e.g. the Rogue, John Day, Owyhee)? I rarely get to fish as much as I want, so wetting a line in some of these rivers is a top priority while I have time away. I should mentiont hat I plan to bring both my spey and SH rod, so I shouldn't be limited by river type. Thanks in advance for the advice.
