Added the local folklore of the 7 Gates of Hell to the map.. Added in some new roads between O'Fallon and Troy, Illinois. Updated the geometry and attribute data of several roads in Placerville, California area (my old hometown). The OSM road structure there is so messed up that I don't know if it will ever look good. I will just keep taking bitesized chunks until it looks right. There must not be any OSM junkies up in Placerville, because I don't think anyone has looked at the road network since the original import.
