Yes, my first thought was, not what you would have wanted to have happen while on the road to or from a filkcon (or anywhere else), and if your weather's anything like ours (which it might be approaching, since the fuel did in fact freeze), especially not what you would want to have happen while on the road at all. (We've been in single digits -- Fahrenheit. With snow. And I realize that sentence was kind of mangled and redundant and not terribly clear -- the brain is freezing my cold. I mean... never mind. I'll try again when I thaw out.)
