getting back to the first continent

[nevermind6794]

I thought I read somewhere that there was a ferry you could take back with the buggy. I have the buggy and the plane (forget the name right now, for some reason) but that's it. Can I get back without having to get the submarine or the airship?

the Tiny Bronco can got to the Eastern Continent by going just south of the Northern Continent. the Buggy can be taken there by driving it directly into Costa del Sol and taking the boat at the dock by into Junon (the one you took over and fought Jenova Birth in)
