Question Mark Rain:-  For this code to work you need to get Washington DC by the levels code or another way. First beat Washington DC in first place so you get Washington DC 2 then start a race in Washington DC 2. When you start the race turn around and drive backwards after you drive for a little while the rain will turn into question marks.
