Took advantage of the slight thaw in the weather today; the advantage of this weather (and having Mondays off work) is that you can often visit sites that may be normally out of bounds - like archery ranges! Went looking for the remains of a Anti-Aircraft camp in the Westleton Heath / Dunwich Forest area - no budding Robin Hood's around today!!
Some remains of concrete bases remain (Nissan style huts would have been built on them) - one is still in use with hut associated with the archery range.
The map shows the outline of bases I found today (may not be 100% accurate as GPS reliability in woodland and with waypoints in close proximity is not that reliable).
