収束ゾーンでのライフ: Life in the Convergence Zone

I used to be in model rocketry, but these days to do the stuff we used to do, you have to have a permit from the BATF!! Can you believe that? Most of the engines we used are all illegal! I was told that this all happened (making it illegal) in the mid 90's, I don't know. Kind of sad. I wonder if there are still model rocketry clubs in any schools anymore?
