The trip back is becoming problematic. Now, we have a flat tire. We have a spare, of course, but the problem is that the spare is not a studded tire, or even a snow tire, so traveling with three studded tire and one regular tire doesn't sound like a safe drive where there is likely to be snow or ice. Today, you can no longer just replace one tire with another, like I used when I was young and foolish, so we'll have to buy at least two tires, maybe four - I'm not sure of the potential problems with having two snow tires and two non-snow tires, or even if they will do that. We are about to find out. We might have to leave three usable tires behind because we don't have room to carry anything more than one spare tire.
