I don't see that it would matter to be honest but I can't do anything about it now anyway.
The place is covered in cameras so they won't be looking for me lol.
I remember I was doing the testing on the rail points from the Paddington rail crash and some Korean guy walked in with a camera, he was a spy and had come in off the foot path, he spent the night in jail lol.
The hse / hsl site was the barracks, the officers admin blocks. Most of the tunnels that were ammunition storage are outside of the hsl site opposite where the gokart track is now. On that corner incidentally there used to be a pill box made from brick, It wasn't in the best state when I was there and the camera hse had hidden in there stopped working a long time ago but I've not been there for coming on 15 years now so it may or not be there at all anymore.
No food storage in the tunnels while I was there as far as i know but a section of the tunnels were used as a mushroom factory for a long time.
There is a truck depot running from the tunnels and they do store certain things but I don't know about food.
There is a lot of the tunnel network never explored since the war ended and the munitions destroyed. There have just been left, a mate from the time i was up there went down some disused ones and found an old corporals hat but other than that the truck company pretty much have the entrance to the network locked tight with lots of cameras.
The whole area up there and around Harper hill has some amazing history, the old collage buildings were a good look around further up but now all demolished.
The fun we used to have during lunch time from collage at the blue lagoon, where all the girls used to go and sunbathe, those were the days lol.
