Chased by a glowing, yellow orb in Lockhart TX. 1975 or 76, in the evening. Looked like the moon

The rash of recent sightings of orbs made me think about reporting this. I can't give an exact date or time. I believe it was 1975 or 76 during the summer time. One evening a friend and I were driving down the road near the high school in Lockhart TX and saw a glowing, yellow orb hovering above the field across from the high school sports field. We stopped the car to look. We thought it was the moon but then realized it couldn't be. It looked to be about 20-30 feet in diameter and about 50 feet off the ground. It started slowly moving towards TX21 and we thought we would follow it. It took off down TX21 towards the Lockhart State Park. It was traveling about 5 feet off the road and allowed us to keep up. When the road dipped at a low water crossing it stopped. So did we. My friend said she was being urged to get closer but I wasn’t so keen. Then it slowly started coming back towards us and I frantically turned the car around and headed back into town as fast as I could. It chased us at high speed all the way into town. We tore into the Dairy Queen at US Rte 183 and TX21 and it was gone. When I told my dad about it the next day he said there was a story on the news about a UFO terrorizing a family who lived in an old 2-story house near the Dairy Queen, flashing lights into their windows, etc. I've searched for an archived story in the Austin American Statesman as well as the Lockhart newspaper but can find no record of this. It may have been on the local news. My dad was stationed at Bergstrom Air Force Base so I wonder if he got the news through those channels.
