Proposals exist for various days in Somerset.
There is also a proposal to make the 29th of July Buckinghamshire Day. This date was chosen because of its importance to the founding of the Paralympic Games movement. The games grew from events held at Stoke Mandeville hospital in Buckinghamshire for British World War II veterans with spinal cord injuries.
The Memorial Mob, a Bucks-based group which creates Memorials to Lost & Forgotten events of the Armed & Emergency Services, felt it was appropriate to honour Buckinghamshire.
