they are on an inset of the map. when you go to the map, in the upper left corner, there's a subway icon you can click and see the subway map. they're just not on the MAP map.
I agree with this-- as mentioned in another thread, I spend way too much time hunting for the street name and it drives me nuts! (mainly because was searching for the one in Alakol yesterday and I think I looked over the map quite a few times and started getting annoyed at my brain!)
Jessabelle... you can enter the street name in the map's search box and it will show you where the street is. I use this feature a lot, since the street names are pretty small and there are so many streets in some areas they are hard to find.
