The West Midlands region is comprised of 6 counties:
Herefordshire (GC3CFPX)
Shropshire (GC3CFQ0)
Staffordshire (GC3CFQ7)
Warwickshire (GC3CFP8)
West Midlands (GC3CFPD)
Worcestershire (GC3CFQ6)
Each of these 6 counties has a cache hidden within it, containing one of six puzzle pieces used to solve a Bonus Cache (GC3CFN0), hidden close to the venue of the UK Mega 2013 - Heritage Motor Centre.
Warwickshire is a landlocked non-metropolitan county in the West Midlands region of England. The county town is Warwick, although the largest town is Nuneaton. The county is famous for being the birthplace of William Shakespeare and George Elliot. Commonly used abbreviations for the county are Warks or Warwicks.
The five districts of North Warwickshire, Nuneaton & Bedworth, Rugby, Warwick and Stratford-on-Avon together form the Warwickshire County Council area, and are within the 1974 boundaries. The shape of the administrative area of Warwickshire differs considerably from that of the historic county, which also includes the now autonomous unitary authorities of Coventry and Solihull, as well as a small area around central and northeast Birmingham.
