I just saw on the discovery channel the MUFON case and I had a similar experience in 1998, I was hunting near the border with USA, several of the people that work in the ranch had told me that they have seen UFO from time to time, but I didn���t believe them.One day I was in a hunting blind just a few minutes after the sun set, and suddenly 3 white lights appear in the horizon(US side) I thought it may be 3 USA aircraft, but they didn���t move for at least 10 minutes, I could se a border patrol Zeppelin near by (that they use for detecting aircraft coming illegally from the Mexican side) as time passed it became dark I was getting uncomfortable as the 3 light didn���t move or produced any sound, suddenly form the lights start coming out a lot of lights (blue and red) flying in different patterns, I thought they had been helicopters but the pattern and speed of movement was much faster a human aircraft can do it, they flew for around 20 minutes (but no one of the light crossed the border to Mexico), and then they disappeared, I went back to camp and check the map of the area, in the us side it was a restricted area, so I believe the UFOs that I saw where a kind of experiment of the US military.my exact location was latitude 28��� 8'10.39"N longitud 100��� 7'31.31"O
