Bumbaugh always liked the challenge of working in a diversity of media, methods, and scale.  There have been clear connections among even the most disparate of works.  What remained for Bumbaugh is the pleasure in the material qualities of paint, ink, wax, clay, linoleum, charcoal, pastel, watercolor.  Bumbaugh loved to create. "Imagination is the most important part of creating…to examine, to explain to yourself the vitality and excitement of all and everything you see and think."

Imagination has preceded knowledge in just about everything and is the extraordinary ingredient in solving the artists’ problems.  To Bumbaugh, imagination is his most precious possession.  Without it he is lost as an artist.
