OK, I've spent quite a bit of time searching, but can't seem to find any info. I remember (I thought the information came through flyertalk) of a car rental program that was seeking to "move" cars from Florida, after season, to their California and Arizona markets around March or April. If I recall the rates were almost free, and the time limits were pretty good. This year I'm thinking about a cross counrtry trip and it seems like the perfect opportunity to take advantage of this, I can't find anything about this at all. Any advice where to check?
