Thank you very much for all your nice comments. I'll be traveling with my son who is a pilot in the Navy. He's actually making his PCS (permanent change of station) from a naval air station in the east to another station near Seattle. So we decided to drive cross-country and spend a week in Wyoming since we both love fly fishing the Green. Unfortunately he can't leave the current squadron before the 9th of November and will have to report to his new squadron commander before the Thanksgiving break. Of course i don't want to miss this opportunity of being together and fishing together since he will be deployed to some wide open sea pretty soon. For me it will be about 7500 miles driving from LA to the east coast to the PNW back to LA. Needless to say I really want to make this trip as productive as possible. Now I'm thinking that... instead of spending Pinedale (and Big Piney of course) for a week we may just fish the Green for two days and move to Montana fishing the Beaverhead/Ruby, Missoula area, then Coeur d'Alene Idaho. djfan made a point "We buckle in with our loved ones and enjoy time together. It's not a big city mindset, but we like it. " Thank you.
Another option that you might consider, especially if you are traveling along I-80 to fish the Green, is to continue on to the Boise area where the South Fork of the Boise River is often at its peak in November and since it is lower in elevation the weather that time of year is often ideal.
Or, given your destination, you could continue right through Idaho and go to the Deschutes in Oregon and fish the Deschutes for trout or steelhead. You might get rained on but you shouldn’t get stuck in any snow drifts. If you made Maupin your base you would have lots of access.
A third option I would consider because of vagaries of western weather in November would be diverting to Yakima which would be right on your way in Washington. That would put you only 2 hours from Seattle so you could fish right up to the day your son needs to report.
As djfan said, Wyoming could be great that time of year. Or it could be in the grips of what feels like the next ice age. You have a ton of good options, but Wyoming (and any Rocky Mountain state for that matter) can become completely unfishable because of snow, ice, wind and temps that late in the year. For example, Laramie is just 19 miles north of the Colorado border, but at 7200 feet. Today we had winds up to 60+ mph even though the temps were reasonable (midl 50s). We have highs below freezing and snow or rain predicted for next week. Who knows what we will really get.
I would keep my options as open as possible when traveling or fishing in the West during November.
Good luck,
Don
