    Retired Engineering Designer, Photographer
    Golf, cooking, hanging with friends, wine, listening to music, working on cars, wood working.
    watching movies (blue-ray) 60" TV with complete surround sound and a very comfortable reclining sofa. Golf, especially with the girls. Love to build custom computers, used to work as a professional photographer doing wedding and model portfolios and some travel stuff. Used to play guitar and trumpet until graduating from college, wish I had kept my guitar (Fender Strat).
