DISCO DAVES TUNNEL GUIDE
Worm holes
The worm hole in the Cliff Richard tunnel at Manchester was a 6 foot long circular tunnel that was little over a foot and a half wide and sloped downwards to the first chamber.
It was easy to get into but difficult to get out of, with protesters from time to time getting stuck like a cork in a bottle. A horizontal worm hole would probably be a better idea. Both options mean a lot of digging for the MIB .
