A ticket that covers the whole system (well, much of it) - that, we've got. It's a smart card called the Clipper Card, and all I hear about it is how baffling it is to use. It's really only cost-effective if you use the transit regularly, which I don't - all we have in this area is bus lines a mile apart that run twice an hour, at best - so I've avoided it with trembling fear.
