Pyrotechnics brought me back to rocketry, although this hobby has been on hiatus after my son was born. It is hard to justify spending a day or weekend when I'm off work, away from him to make a few dollars setting up public displays. It is also much more difficult to build in a safe and legal place. I'll return some day. With my son, I can still enjoy outdoor activities like mountain biking, hiking, kayaking, and skiing. So far he has enjoyed doing all these with me and I love being able to show him hobbies I have enjoyed most of my life.
