Greg McKennzie was tooling around the countryside in his '69 GTO when he saw a roadside produce stand and decided to stop. He pulled his car off the road and joined maybe seven other people in perusing the peaches and appraising the apples.
Even though there were only a few other people present, Greg eventually noticed they were staring at something behind him. He turned around and stood dumbfounded.
About three hundred yards away was a craft of some sort, gliding toward them. It was spindly, looking like a boomerang bent at a sharper angle, and with a third 'spoke' radiating out from the center, equidistant from the other two. Its diameter was about thirty feet, and it moved in total silence. With nothing in sight but bare fields and the one road, it made for a very eerie scene.
As it approached, Greg noticed the underside was not smooth, but riddled with wiring, tubes, ports...it looked industrial and very complex. Behind him, he heard a car start up and peel out, roaring down the highway; he thought that was probably a good idea and started backing up to his own vehicle. At the door he paused; an old man walked to the center of where the craft had stopped, twenty or so feet above the ground, forty feet away. The old man looked up, more curious than scared.
A pole telescoped down from the center of the craft and stopped about a foot off the ground. There was a disk of some sort on the end, which started to hum.
Greg called out, "Uh, mister, you might want step back."
The old man looked back and nodded, suddenly realizing he might be in danger.
At that moment a plane of energy flinked into existence, centered on the disk and radiating out to the edge of the main craft, about thirty feet in diameter.
From his vantage point, Greg saw the old mans' legs, from mid-shin down, topple over, neatly cauterized; at the same moment the old timer, now unsupported, sank into the plasma disk, sizzling out of existence, like a candle placed on a super-heated metal surface.
He didn't have time to scream.
Without hesitation, Greg got into his car and headed for the city, constantly checking the sky behind him.

By the time he reached one of his favorite restaurants, the 501 Diner, Greg had decided to not tell anybody what he'd seen; he would just be taken for a nutcase, and didn't want to risk being arrested for causing a disturbance.
He wondered if what he'd seen was just a test of some sort; such a small-scale attack seemed inefficient.
On his way into the city, he had tried to reach some friends on his cell phone, but the service was out; even his car radio reception was sporadic at best. Now, sitting at the counter, he noticed the television in the corner was showing nothing but static.
When the waitress brought his coffee, he ventured a question.
"Hey, uh, have you guys noticed anything strange today, military on maneuvers, buncha helicopters buzzing around, stuff like that?"
"No, sugar, nothing like that. TV and phones went out 'bout an hour ago, but that's about it."
"Okay, thanks."
His phone still not working, Greg picked up his coffee and headed out the door. He had no family in Houston, but he thought he'd check on a friend of his who lived on the other side of the city.
When he stepped outside, he looked to the east, dropped his coffee, ran to his car and took off west, as fast as he could go.
Not really conscious of what was going on around him, Greg peripherally noticed that there were indeed military aircraft overhead now, and other motorists apparently had the same idea as him. Still others seemed to be speeding past him in the opposite direction; Greg knew that were going to regret their curiosity, but he couldn't help them.
Before he knew it, he was miles outside the city proper (having passed several National Guard trucks along the way), on a piece of land slightly above the city.
He got out of his car and stared as a massive alien craft, many, many times bigger than the first one, slid into position over Houston. He didn't know how big the city was, but this craft was easily big enough to cover it completely, with room to spare.
Greg waited for the inevitable.
After a time, it started. He saw the tube as it descended, apparently down into the ground this time, then heard the rumbling hum as the entire city skyline appeared to vibrate. Giant plumes of smoke and steam rose up, partially obscuring the view; then, amazingly, the whole city began to sink into the ground, like it was nothing more than a model being lowered on a platform.
Within five minutes, it was over. Ten minutes later, the smoke cleared and revealed a perfect, massive hole in the ground; the size was nearly incomprehensible, and its neat, smooth sides added to the surreal nature of the abomination. Nothing was left; roads just ended here, and reappeared there.
Greg slowly got into his car...and just sat there; he didn't know what to do.
The craft started to drift to the north...
