Until whenever do us part

When traveling, I don’t like committing to much in advance. I don’t make hotel accommodations until I know what train I’m arriving on, and I don’t know what train I’m arriving on until I know what city we’re going to next. And I don’t know what city I’m going to until…well, you get the idea: when contemplating tomorrow on the road, I prefer waiting until today has more or less become yesterday.
