I guess I expect it to still be available at certain places. As far as I know/remember it was always available.
But it was never "out front" under the control of a 16 year old kid with pimples, working the counter in the Grainge Co-Op or whatever.
If you wanted to buy dynamite, there were always the stern eyebrows of the senior manager who would want to know exactly what you had in mind, involved in any dynamite sale. You better be serious and very sober and be able to explain yourself very clearly, if you expected to buy dynamite in the places I am familiar with.
Mel Brooks would easily be smart enough, but I am not entirely sure he could have put on the proper demeanor. Maybe he could have. I didn't know him personally.
Government documents may be involved now, but frankly I don't trust them as much as the old system. While you do hear stories of fools with dynamite, those stories are few and far between.
I wouldn't be surprised if it was about to get worse instead of better.
Fooling lowly paid gov clerks (to get permits) is never that hard.
Getting past the old man in the back room? Nobody did that easy.
