Photography is a hobby - my wife hopes it will keep me off my motorcycles. I have had fun in the last few years. I do not have much time to take pictures so I am a little slow to upload. I try to upload to 500px the best of my shots. Hopefully you enjoy. I maintain a family web site at which has all of my photos and more pictures from trips we have taken and portfolios from travel. What I consider my best photos I put on a photoblog site I developed to add additional comments about how I took the shot. If you like enjoy The site has most of the features of a photoblog - comments, RSS feed, and an About Page with info on me and my equipment.
