Another Killjoy, the professionals have to learn somewhere, if kids can't blow up and burn down their neighbourhood, what's the point of being a kid? My cousin and I blew **** up all the time! My cousin used to make explosives in his mums bath, he got a bit nervous with some nitroglycerin he made one afternoon so we buried it in the paddock out the back. 7 or 8 years later they built a road through that paddock and the nitro nearly blew up a truck. We were very impressed with it. All sort of uniforms came out to investigate, there was a crater the size of a minivan. Sensational fun.
We made pipe bombs that set off car alarms and broke windows, it was all a healthy part of growing up. We're both well adjusted moderately successful adults these days, if I called him up tomorrow and said lets go blow something up, we'd take an ages to find a hole in our schedules to do it. We never consider the freedoms we lose with "success."
I find these professional shows a bit sterile, there's no danger, no pissed off neighbours, no hospital admissions. No fun.
