If we get one, I'll be buying one new, as we don't really know that many people up here that I could get one from. That said, I work in childcare, so there are plenty of families around me that I could trust with one.
We did toss up specially booking taxis with capsules, and this would be a really good option for us, because - trust me - we don't drive.
For visiting my sister, we have thought about hiring one. Actually, we have thought more seriously about hiring a car to visit her, and doing away with our car altogether.

BeautifulMadness: I'm really interested in what sort of "just in case" moments you mean? Just so I can really thinka bout my options and come up with the best choice.
