The boundary of Castle Donington at the Southern end of the village. This is located on the airport trail which takes you around the perimeter fence of EMA.
When the aeropark is open, this is a great cache and dash. When it's closed, you will have a little walk as most surrounding roads have double red or double yellow lines - try parking on Diseworth Lane.
This may be an obvious hiding spot, but it is a well disguised container so hidden in plain sight.
Tweezers may be required.
