You should have been able to take a Smiths or Native Son ferry out of CA, if not a RTFF. I think the taxi guys may have just wanted a higher fare. It's not hard to have them stop at the CA terminal on their way to check what's still available. This is why we like to use Kevin for STT taxi service. He knows exactly what is available and he even helped line up a Speedy's late ferry for our group when the last Smith's was full and Speedy's dropped us off at RT on their way to VG. Kevin is de man!
