UFO seen in 1975 on a desserted hwy. in NC

It was summer, in 1975 when an object followed our car for miles on an empty highway road and the UFO followed us for 15 minutes so we stopped and pulled off of the road and all three of us got out and the UFO pulled up beside us and stopped and hovered above the tree tops about 250 meters away from us and the UFO had multicolored lights that flashed around the mid-section sequencially, Purple,red,white with weird speckles of light inside of it,yellow,green, etc. It just hovered for a long time and the lights turned purple and the lights reversed direction and and flashed in the opposite direction. Then it started to land just behind a few trees that were widely spaced apart and it landed on the lawn in a field across from us which was approx. 250 meters from where we were at, and we got scared and got back in our VW Beetle (New) and we got out of there. It was very terrifying at the time and we were very scared about what happened. There was no one around at all, no cars, people, etc. Nothing at all. I just wanted to share this experience because I think we all have been in shock and disbelief for so long about this experience. I am just now decideing to share my information about this incident.
Date is approximate.  PD
