Portland, Salt Lake City have pretty good connections. Seattle also if you don't mind walking through the parking garage (often security will snake back to the lightrail station, you know you are in for a bad day). SFO has Bart to the airport, Caltrain is also possible but you have to connect to Bart for one station. I admit that I've been to SFO a few times and have never bothered taking Bart (in contrast, I always take Max from PDX).
