numerous UFO's erratically streaming from red rock formation "guarded" by gov't black helicopters

Some friends and I were doing some hiking/hanging out on Schnebly Hill in Sedona, Arizona sometime during the month of May in 1993.  There were approximately 10-20 of us all around the area. It's been more than 10 years, so I'll do my best at decribing what I can remember. I only just found this site today (07/19/04).
 I was living in Sedona at the time, and my friends and I loved to go hiking whenever we could. We had heard many stories of UFO's, but most there had never witnessed any personally.
 A couple of my closest friends and I were inside the van which was parked at the top of Shnebley (sp?)or as close as we could get. There was a sort of pseudo rocky parking lot which we used as a "base".
 I don't remember the exact time, but it was near dusk and I was inside the van with a few friends. All of a sudden someone pulled open the sliding door and screamed, "you've got to come see this....there are some strange things going on out here!"  So, of course, we all piled out and walked to the end of the "parking lot", looking towards the major rock formations directly across from us (I can't remember the name of the certain formation now). They were all pointing across the way to what looked like two black helicoptors which were looking like they were "guarding" either side of this strange rock formation. This is so hard to explain, I wish I could remember the name of the rock...you'd know exactly how it was set up.
WEll, just then, the middle flat front face of this rock formation all of a sudden disappeared while the black helicoptors just "stood guard" on either side of the "cave" and UFO's stared flying out of the new formed "cave". The UFO's were fling very erraticly, hard to count or follow a certain one. They continued to zip about until all were out of the "cave". Then in a flash they were here, then there, then zap! gone! no where to be seen! Then, the rock face closed back up and the black helicoptors waited a few minutes and took off.
 All of us were stunned, needless to say. We didn't know what to think and all of us had our own descriptions of what we saw, but we all agreed that we had witnessed something none of us could explain. All of us all felt an unnatural "buzzing" like a different frequency disturbing the area.
 During the next few months of living there, I encountered many sightings of black helicopters, strange stories of "government men in black" turning away hikers in certain areas and caves, and even a strange underground explosion, or earthquake, or something...(none who were with me ever heard anything in the news about an earthquake or explosion underground in the Sedona area).
 I still don't know exactly what we all saw, but it was definitely something all of us witnessed that we had never before imagined or could deny.
