The next time you're working in the yard and using weed killer, you just might be doing something else that would never occur to you. You could be helping Dennis Albaugh add another car to his massive collection of Corvettes and Chevy muscle cars.

How so? Well, Albaugh has built and heads up an international agricultural supply conglomeration with products that use the chemical glyphosate. It's the primary ingredient in one of the world's most popular household and commercial weed killers, and it has made Albaugh a wealthy man. A billionaire, in fact.

When money is no object, it's full steam ahead to pursue one's passions. And one of Albaugh's passions is collecting the aforementioned Corvettes and muscle cars.

The collection is housed in an enormous purpose-built structure that holds a dazzling array of cars and automobilia. There are well over 150 vehicles in the collection; all Chevrolets, and almost all convertibles. Several dozen are Corvettes.

Not a top to be seen in this line up of C2 generation Corvettes. The roadsters are part of a huge collection of Chevrolet muscle cars owned by Dennis Albaugh.

"When I was a teenager," the former Iowa farm boy says, "I wanted a Corvette. But my Dad said they were too fast and too dangerous with all that fiberglass, and he wouldn't let me have one."

So, he had to wait a few years. Today, it's instantly obvious when walking into his 28,000-square-foot "garage" that he's made up for lost time.

Presented in razor sharp lines of display, the Corvettes mainly represent the first three generations of the brand.

Prime examples of the Corvette's first three generations can be seen in one part of Dennis Albaugh's 28,000-square-foot "garage."

"When I started out, I was really just looking for a nice '58, '59 or '60 Corvette. Those are my favorites," he says.

His search was fruitful, and Albaugh acquired all three. By then, he was smitten, and the collection was off and running. He has a complete set of Corvettes from the first in 1953 through the 1972 model. There are also a few later model Vettes in the mix.

Multi-colored third generation Corvettes are meticulusly lined-up behind stand up displays with history and details on each car.

While the collection is all Chevrolet, it's not all Corvette. He has pristine examples of Camaros, Chevelles and tri-five Chevys, and most are muscle cars.

Additionally, he has drop-top samples of every Chevrolet from 1912 forward. One exception? He doesn't have a 1939 convertible from the U.S. because Chevrolet made none that year. They did, however, produce a half-dozen or so in Australia. They were equipped with right-hand drive, and Albaugh acquired one of those and restored it a few years ago.

The history and the maintenance records for all the cars is computerized, and on-staff workers keep all the cars in top shape, ready to go any time Albaugh wants to take the car of his choice out for a spin. On most weekends he's in town, that's a given.

For the purist Corvette lover, there is plenty to feast your eyes on in the Albaugh collection. Unfortunately, the collection is not open to the public — except for one day a year, usually in the summer. A one-come-all car show is hosted on the grounds, and his garage is open for all lookers. Admission is charged, and all proceeds benefit the local school athletic programs.

The crisp lines of Corvette's first Sting Rays never fail to catch visitors' eyes in the collection of Iowa businessman Dennis Albaugh.

Oh, and when Albaugh has a little time but doesn't want to drive one of his dozens of classics? He plays golf on his personal regulation-size 19-hole — yes,19 — golf course. It's a country club with a membership of one.

Albaugh never has to wait for a tee time. And there's not a weed in sight on the course.
