There will be plenty of muggles around during the week, take care.
In 1988 I worked in the workshop across the street, after a party here we crashed into the wall at the bottom of Hillcest. I spent 3 weeks in a coma and ended up writing a book about it, Learning the Hard Way - Matt Bullen.
During the weekend you will be able to park right next to the cache.
A small systema, has a log and pencil, and items to swap.
