Anyone have a Prius?

Part of what I love about the car is that one bike goes in the back, easily, with the front wheel on and everything.

But when we fly south for the winter, I don't think there's going to be room inside for the bike *plus* all our stuff. I've driven 1000 miles in a small car with a roof rack before, and don't care to repeat the experience. But I've also been warned about putting a bike on a rear rack when there's salt and cinder on the roads. One guy I know says he's wrapped his entire bike, rack and all in packing plastic. Okay... but for a two-day trip, where I'd have to take the bike off for the night, there's probably as much petroleum in a second round of plastic wrap as I would've used to just drive a freakin' Suburban with the bike inside That stuff is not reusable. Plus, what a PITA.

I'm half thinking about shipping the bike. I'd have to get a case of course. What do you guys think about that? How much of a pain is it to disassemble/reassemble for shipping if I don't have a workstand on either end of the trip?
