When I was a teenager(late 70's), I had a few rocket that I occasionally launched. Nothing special - I don't think I had anything larger than a "B" engine. Now at 41, I'd like to try it again with my fiancee's kids. The girl is 10, and the boy is 4. Are they old enough? I figure the boy can at least hit the launch button from a safe distance. Does anything like those old rockets still exist? If so, where are they available from? I'd also need to find a decent launch field in the Detroit area. A few quick websearches have come up empty. Any assistance is appreciated.
