World War 2 Remains

Someone with an untrained/uninterested eye may have just driven past this without a care.

To me, who is a very big history fanatic they may do the following.

Screech to a halt
Grab camera
Leg it back up the road
Do a strange little foot shuffle whilst setting up camera in excitement

The plaque says it all really as to what this is. Locally there are many many remains from WW2 such as airfields, shelters, gun placements and what not to full blown derelict RAF bases. You'd be surprised what's still left hidden in the undergrowth.
