Here is a quick save ideal for people who want to enjoy the story with minimum exploration. You will need to have completed the Prologue and 1st missions (You'll have Welcome to Los Santos unlocked). The save starts you in a helicopter, switch to the map and you'll see one small black mass covering the area in front of you. Simply fly straight across this to the other side to unlock San Andreas Sightseer. Now you can enjoy the rest of the game without needing to do any more exploring.
