I'd like to say I jogged back and got it (that would be a real hardman !) but I always go with a couple of mates and we set the cars before we start (have one ready at the end for the drive back). Then we all meet up at a mates and sort all the gear back out into the proper cars and relax with a few coldies. Luckily he lives a few minutes from the beach. When he's not around we do it at the car park but not as much fun then.
i often wondered how those google earth gps patterns were made, then i found this

unfortunately, the best i can come up with is a day where the wind turns 360 degrees
