Lex, I work at a leading reasearch facility for Dark Matter, called SNOLAB. We’re located 2 km underground, in a 100 year old mine, making us the deepest clean lab in the world. They are starting to give more tours, I am sure they would be happy to give you one with the topics you cover in your podcast. If you had a podcast here, I believe  it would make it the deepest podcast ever recorded. Think about it.
