I didn't make it to the preview last night, but heard good reports from my father who did. I will remind you to go to this exciting exhibition based on new research. Some of the material has was presented at the Trust's Underground Stockport lecture, but much of the material is new.
In presenting this to the public, I anticipate it generating further research, either broadening the scope of the studies or or taking a more detailed look at research. There may be more maps and primary sources, or access points to Underground Stockport than we currently know of.The Trust, in particular Coral and Kevin Dranfield remain interested in more data and are keen to add to the body of knowledge.
So get down to the Exhibition soon and expect to learn a lot.
