I am fully aware that the reason why the world map of every GTA game is depicted as an island despite the fact that they're supposed to be fictionalized counterparts of real places in the mainland US is for technical reasons, as Rockstar decided to circumvent the problem of invisible walls by simply not having any non-playable areas, and having the playable area be surrounded by water.
But I like to think this is fully diegetic and in the GTA universe the United States is just a gigantic archipelago. It's an entertaining thought.
