This is the quickest cache and dash possible - you will need to open your car door but not much....
When you enter the carpark, I recommend that you keep hard left and park next to the single information sign. This will help shield your actions if anyone else is in the carpark at the time.
Once you have found the cache then take time to enjoy the Westbury White Horse which legend says was cut to celebrate the most decisive battle between King Arthur's Anglo Saxons and the Vikings, hence altering the entire path and culture of England.
I placed a cache here in 2004 which I archived many years ago, then noticed recently that there is a gap - although Ailec Nor have "White Horse View" a little further along the track.
