Damien,
All the EVP's we got there with the exception of one are of a small child, maybe 10-12 years old. I have them posted on our website if you want to check them out. The other EVP is a man saying the name Mary. I'm not using anything fancy up there for EVP recording, just a Panasonic RR-US320 digital recorder with a good quality omni-directional mic. We have bever experienced any thumping on the ground there but there is a very distinct smell that comes and goes, it is the smell of Camfer, Camfer was used as a remedy for chest congestion a long time ago, kind of like Vicks Vaporub is now, it was used quite a bit on influenza victims. the part that makes this smell interesting is the fact that two of the EVP's i recorded there from the child make references to being ill, the first one he says "I'm sick" and one investigation later i asked "how did you die?" and the response was "Got the flu". this is interesting because an influenza outbreak went through that area in the mid to late 1800's and all the graves in that part of the cemetary are from that time frame.
