Prize fighting was once a popular past time in Flash, and continued long after it had been made illegal. Fights often took place at Three Shire's Head, a local beauty spot, containing a graceful packhorse bridge and small waterfalls, situated about a mile north west of the village. It is the meeting place of the 3 counties of Derbyshire, Cheshire and Staffordshire, hence its name. Flash was also noted as the centre for counterfeiting money, which became known as 'flash' from its place of origin.
