This might be a good location to revisit in the future for refactoring. Line 17 passes in 'rain' and then line 18 runs a `rain` method. If you needed to change rain to "snow" or "precipitation", you would have to change this in two places. You might recall that today, but the DRYER you get it, the easier it is to maintain 6 months from now when you come back to the project and don't remember how it works.
