I'm just playing with Google Maps.

[randomness]

100 busiest world airports by total number of passengers emplaned or deplaned, passengers in transit counted once, 2007, from Airports Council International, displayed as placemarks in Google Maps.

Subway systems with more than 100,000 riders per day according to wikipedia and mic-ro.com/metro, displayed as placemarks in Google Maps.

Great stuff. I wouldn't have guessed that Santa Domingo or LA would have qualified as cities with busy subway systems.

100,000 riders per day is a relatively low bar, but I wanted a lot of dots. :)

Neat! Thanks!

I have a strange feeling I've seen it before and gotten an account, but I applied anyway. :)
