I have been commuting from
RNO to SFO for 10 years. At one time I would almost always fly. Either to SFO or OAK and BART over to SFO( BART is dirty and dangerous in my opinion).
I now drive about 85% of the time three times a month. I allow 4 hrs. My 4 hrs is based on missing the peak traffic times. I have taken as long as 8hrs. If I fly out early. I get a hotel the night before.
I am looking into getting a RV-7 to
fly myself. That alternative will work maybe 6-7 months a year. Mostly due to winds over the Sierras.
Good luck with your choice.
