The series of US railway crossing challenges on MapRoulette is now 
complete!  Thanks to the many people who helped with this project!   The 
topology of the US rail-road intersection areas is now much more 
accurate, since many of the crossings also required a geometric 
alignment of roads and rails in the area.  I'll write a diary entry 
later with more details when I get time.
