No I haven't. I've only read a little bit of that thread, but it certainly sounds interesting. I might check out the download after the holidays. I can't budget any funds into anything that isn't related to either the holidays or my home's fuel tank.
PS I haven't seen the The Secret either, but I think I get the basic concept. I've seen Dr. Wayne Dyer's "The Power of Intention" or something like that. But MDC is the first place I've heard of treasure mapping.
