Ghost BMX is a proven glitch and a possible myth in GTA San Andreas.
Description
Under the waters of Santa Maria Beach, a standing BMX can be found. This is the only known location for the Ghos BMX to spawn. Most fans believe it to just be a spawn glitch, wherein the game spawns in a BMX rather than a boat. However, there is a small group of people who believe the BMX to be mythical, they back up these claims with other "intentionally" placed objects found around Flint Waters and the Flint Range, including the Ghost Traffic Light. The BMX is driveable if the player is using the underwater glitch.
