What a superb production!  Thanks so much for taking the effort to model this as the real 1967 was very wet indeed.

I should
mention, tho, that real-life rain racing at Mosport is about 30 seconds per lap slower than dry times.  Yes, that much.  I speak from direct
participation experience and a half century of specatating at Mosport.  I wonder if suitable textures are available that will balloon laptimes to
that degree?
