Narrative:

I always insist that I be in the cockpit and copy clrncs when the first officer gets it so 2 minds are applied and I usually check the route then. This time the first officer got the clearance alone. No bd. Flight oak to lgb usually gets an offshore SID with a made up transition to big sur 131 right, thence to the catalina 107 inbound. When I hurriedly copied the clearance from the first officer I didn't pay full attention to the transition which had been changed to flw, tandy 2 arrival, due to vandenburg range space in use. First officer's leg, he flew our normal route, bsr 131R we were 10 or so mi off course before center asked us our routing. His leg, my responsibility and complacency, routine and inattention lead us astray.
