"Drive to each bus stop until the target is located" is an objective in the Hobbies & Pastimes mission The Bus Assassination in Grand Theft Auto V
Walkthrough[edit]
Now is the tedious part. You need to travel from marker to marker to find your target.
Stop 1:
The first stop is just up Sinner St. Go right then make a left on the next street to get over to the stop. Hit the marker and stop.
Stop 2:
Go forward 2 blocks then make a left-hand turn on Vespucci Blvd. From there it is another 2 blocks to the next stop.
Stop 3:
Make right on Sinner St then another right on Adam's Apple Blvd. Go up 2 blocks and you will see the marker.
Stop 4:
Make a right onto Strawberry Ave. Take that up until you reach San Andreas Ave. Turn to the left and head to the next stop 2 blocks up. Here is where you will find your mark.
