On the evening of March 30th, 2010 I was going out to dump garbage in the village I live in and a bright light caught my eye to the right of it. The direction was Northwest of Box Elder MT. I didn't exactly think anything of it until I noticed that the object was changing color ranging from red,orange,blue and white. The object seemed to be dropping at a slow pace. It was around 9 o'clock at night when I first noticed it, so I called my brother whom lives across the street from me. I told him to look out and look towards northwest of Box Elder. My brother and my Mom saw the object also and both can give a similar description of what we saw. The object changed colors and also seemed rotate as it was decending downwards. This is a first for me as I never seen a UFO before, but have heard many stories around here. The whole thing took around 40 minutes to happen, the object disappeared suddenly before I can get a picture of it.
