In due time, Howard was a regular participant at the shows in the Los Angeles area. Not only was he showing off his Chevy, he was taking photos at the show of the other cars on display. Various show promoters like RG Canning, Bob Shrimp, and ISCA were hosting shows at the Great Western Forum, the Los Angeles Sports Arena, and the Long Beach Convention Center during this time. Howard kept the '67 Impala for about a year after he completed it before ultimately selling it with the intention of buying a 1969 Impala. When the 1969 Impalas arrived at the dealerships in the fall, Howard paid a visit to Cormier Chevrolet but did not like what he saw. It was time to move onto "plan b," which was to locate a Buick Riviera. A few weeks later, Howard located and bought a 1966 Riviera. Almost immediately, Howard contacted Dick Sellers of the well-known Dick & Ron team to install hydraulics in the Buick. From Dick's shop, the Buick went to Bill Carter's shop in Van Nuys, California. Bill did a full metal flake in fuchsia and silver with "vailing" over the silver and fogged the highlights. Walt Prey was once again called upon to stripe this car. Being a Buick, Howard thought it should have OG Buick Skylark wire wheels. There were no reproductions at the time, so he had to round up five old originals. After spending around $200, he dissembled them, chromed the pieces, and then had a guy in Signal Hill, California, named Joe Worsey lace them up. Joe was the go-to man for that sort of thing, and he took them home and worked on the wheels while watching TV.
Photography was quickly becoming an art form rather than a hobby for Howard, so he purchased some pro-level Nikon bodies and lenses. Howard's increasingly consuming interest in photography, and his desire to learn how to fly a plane forced him to sell his Buick. He stopped Lowriding around 1970, and with the proceeds from the sale of the Buick, he pursued flying lessons. In 1973, he got his pilot's license and bought and restored a World War II-era SNJ plane. It came out of a junkyard in Japan and was restored to original condition. Howard described it as "the aircraft version of a Lowrider Bomb."
Around the same time Howard was restoring the plane and taking his flying lessons, he started to notice a lot of gang graffiti around his neighborhood and in other areas of Los Angeles he frequented. There were a lot of different styles of graffiti being painted on the walls. He felt that the graffiti would be an ideal medium to document, and maybe publish a book about it someday. While documenting the gang graffiti, Howard was very discrete and shot most of the images from his car. He called this method "the drive-by" method. Sometimes he didn't even stop rolling. Most of the photos documenting the gang graffiti photos were taken between 1970 and 1975. As with his photos of Lowriders, Howard has quite a collection of gang graffiti photos.
Around 1986, Howard sold the plane; it was time to devote his time to other interests. Never one to be idle, Howard kept busy throughout the years and traveled extensively. He has visited almost every state in the U.S., and has also visited some foreign countries. As a man of many interests, Howard has been involved in art projects of some kind for most of his life.
