Whistle Brook forms in Pitstone and joins the River Ouzel near Slapton, which then joins the River Ouse at Newport Pagnell, which then joins the Great River Ouse. The water finally flows into the Wash in East Anglia where it enters the North Sea.
As a child I lived in Great Gap and spent many years walking this section of road every day in the 1970s, firstly to Primary school in Ivinghoe and later to Ivinghoe church where I got a bus to Secondary school. This section of road was hazardous (it was national speed limit and there are few places to get off the road to escape speeding vehicles) so I was very pleased to see first a 30mph limit and then a footpath created through the fields in 2011.
You will need to park in Ivinghoe to find this cache - there is no safe parking nearby and it is NOT a cache and dash.
The Little Bridges series was started by Stanthews in 2009 to highlight small footbridges in remote parts of Wiltshire. Since then the series has been expanded by others all over the country and starting to spread fast, Damian from Winter Foxes has created and updates a list of cachers who has found 10 or more little bridges and can be found here, if you would like to add to the series, please contact Stan on stanthews@aol.com and he will give you a number for your bridge, to qualify, the bridge must be a foot bridge too small for vehicles, please make sure your title exactly matches “Little Bridges # xx then name” including spaces so it will get picked up and added to Damian’s list.
