Hello all. I'm a student filmmaker from the United States who wants to take a trip to Paris to explore the catacombs, tunnels, and other underground spaces and to learn more about the people who explore them. I plan on heading over around the end of the month, but I don't have anybody who can act as a guide or who would be willing to be interviewed. I've been very fascinated by these sorts of things for a while and feel compelled to explore them. Can anybody help me out or give me a pointer on how to get started or find other people wiht this interest?

Thank you very much!
