el dia de expropiacion petrolera in San Pancho

Today is sort of a holiday here because we are observing the expropriation of the petroleum industry by Lazaro Cardenas. All we have done so far to celebrate is have a tank of propane gas delivered. (Propane is derived from petroleum, right?) I'm not sure what else we could do that is petroleum-related to mark the occasion. We had a burner on the stove fixed last week, but if I had know today was the big day, I would have waited. Maybe we could have a party...hmmm....having trouble thinking of how to work petroleum into a party theme. Any ideas?
