I've been into model airplanes as long as I can remember. I dropped out completely for about 10 years for education and job reasons. My oldest son got me back into modeling. I stayed in pretty avidly for about another 10 years. Then I went through the mid-life thing and decided to set up a research program which involved a good deal of foreign travel and working weekends. However, I kept my AMA membership up. I got the research under control after about 6 years, and became a department chair. When that happened, I took up modeling again to keep my sanity. Now I am retired and really enjoying modeling.
