If you are watching from the top make sure you're well out of the path the driver is comming up. Even if you think you're out of the way the driver might not.
There's nothing more annoying than having to change your line up an obstacle you're already unsure of becasue some moron wants to get a closer picture (the bad thing is that its usually a family member or friend that you have to tell to move the hell away). :rolleyes:
