My best friend growing up was Stephen Pollak and we would build and launch rockets. His dad Steve would always have time on a Saturday to take us to Grayson Stadium for us to launch our rockets and test new capabilities. We started normally and overtime moved to improvise by adding cameras, more rocket boosters, more rocket boosters, and just see what would happen until the rocket was not constrained to Grayson Stadium and the surrounding park and either threatened the traffic, we could not find it, or it exploded.
I doubt I am going to resume this hobby but I very much enjoyed it as a youth as well as my time with Steve and Joey.
