My 200th passive trig in its playpen overgrown with weeds and no longer photogenic.

The FBM could just be spotted due to the amount plant growth. The "playpen" protected the FBM.

I was cycling past and noticed that the footpath sign has been moved and was surrounded by concrete blocks. Initially I thought the playpen had been removed and the FBM destroyed but it's behind the hedge safe and sound and particularly clear of vegetation at the moment.

Not as much fly-tipped rubbish as the previous logger found but still plenty there. Cleared out anything from the playpen and did a little gardening - cut down the thorn tree growing in there. No height tag, first FBM I've seen where it's fixing point is on one of the side plates. Top has an oversized bolt affixed. Photos at:

In its cosy cot surrounded by rubbish and someone done some fly tipping as well. Couldn't find the cache for all you geocachers out there.

Condition good, but enclosure used for garden waste disposal, and also an old pushchair on top of the block. Photo showing the block (taken after rubbish and vegetation cleared by Jon Glew) at http://www.geograph.org.uk/photo/3769891 and wider view at http://www.geograph.org.uk/photo/3769915
