Short for 'Sheffield Post-graduate Occassional Orienteering Klubb', SPOOK is a club made up of former members of ShUOC. Once you graduate, you are entitled to join SPOOK.
Each year around the end of November, the SPOOK weekend is held - a weekend for SPOOK and ShUOC alike to meet old friends. This weekend involves an orienteering relay, a formal dinner, a football match, captains memorial in a pub (usually the Grindstone, previously the Notty house), and post-drink drinks at the captains house.
