I was a pizza delivery person back then, working for Rossina Pizza in Mishawaka, Indiana(they still are open). I was driving westbound on Mishawaka Ave, crossing the St. Joseph River. To my north, I noticed a craft, flying low, traveling to the northwest. I turned my car north onto the first road west of the bridge, turned off the car, and rolled down the windows...I wathched this circular craft drift over the river, just above the trees. It had yellow and white lights blinking around the outer circumference, there were NO sounds from the craft. I watched it until it went out of sight. When I completed my delivery, I went back to the shop and told everyone!! They wanted to know if I saw any Purple People!! Today, I live in Miami, Florida. I am the Natural Areas Manager for the county and have a BS degree in Biology. I'm not a kook, this really happened. My family knows, I just thought it should be recorded by you guys for posterity.
