INTERIM BOLs

[Paul]

Good plan NR.
I've been visiting old WW2 sentry boxes and old bunkers in my area for a while now.
None of them are exactly NBC / CBRN proof but mostly way off the beaten track.

I even found an intact cold war prefab buried NBC shelter in a wood by following a bunnie one night.
If I had the time, I'd replace the door and as a BOL it would be perfect.
Only one small problem though, it's on Forestry Commission Land.
