    Hobbies My parents owned a Texaco service station, and I grew up there from a young age and had the great fortune of having some very nice muscle cars in my high school days, which lead me into my main hobby to this day. Building Hot Rods, and at one point I had a full time hot rod shop (chop tops, custom body work metal or fiberglass, paint designs and paint) along with my full time main job. I’m also a caricature, wildlife, and hot rod artist.
