history: I had decided to go visit my brother out of state by driving, but as soon as I got on the road it started snowing heavily.  The farther I drove the worse the snow got, and I was unprepared for it.  I was in a very rural area, hundreds of miles from a major city, and the snow started covering up the road such that I couldn't even see the lines or where the ditch started.  I ended up turning back and cancelling the trip.
current: I had to cancel a trip to see my brother after it started snowing heavily.
next: Actually that has happened to me, during Thanksgiving
