EDIT: Never mind. I found the name. It's "Liberty City", but I don't think it exists anymore in either of the mods sections in the forum. I lost a map mod, and I'm trying to find it again. As I recall it's modeled after New York, divided into 2 or 3 separate islands, has an airport at the far west end, and overhead train tracks on the far east end. The larger city part is in the center with the tallest buildings. The east and center islands are connected by a two-tower suspension bridge. There are tunnels under the city that connect the islands. Toward the NW section of the map is also a large football stadium, but I can't recall which island it sits on. There is also a subway underground that goes in a big circle and connects all the islands, with 4 separate stations. One is just outside the airport. That's about the only way I remember how to describe it. If someone knows what the name of that map is, and/or if it's even still around (i.e., compatible with the latest version of the simulator), please let me know. Thanks.
