While I don't have a collection of tinfoil hats, I do have the unusual hobby of collecting various bits of propaganda materials. Some of the collection dates back to the 1920s. I probably have the largest collection of Chick publications, American/European Antisemitism materials, Fluoride propaganda posters and various publications on how the Government is going to get you.
As a kid, I would read any UFO/Flying Saucer material I could get my hands on in my local used book stores. In college, I had access to some great instructors in the sciences as well as in esotericism and religion. I've several Academic degrees, but found traveling most of the planet to be a more useful education.
I believe there are many things that predate our known history or are just plain lost to us. I've been to some of the same places that many of the authors of the books I read as a kid and found those authors to be out for a buck at best... liars at worst. I've seen and worked with advanced hardware while in the armed services including spending a lot of time at China Lake.
Have I seen some very strange things that I can't find an explanation? Absolutely. My existence prolly being one of the big ones as I am very strange. It kinda goes along with two of the most annoying questions I was always asking my instructors, "Why?" and "How do you know?". Annoying because, they then would have to teach me what they knew and which often led me into weeks of sitting in on lectures... uninvited.
One of the primary reasons I enjoyed Art Bell was his ability to entertain the possibility that something a guest presented might be true. He would probe the subject until enough information was shown to allow the listener to decide if it be true or no.
Conspiracies? Yeah, I'm sure there are a few. Like many of you, I've done my homework on many a conspiracy theory. I don't buy into very many of them. Then again... I'm from Missouri.

again... sorry for the post length. enjoy.
