Funny story (since the statute of limitations has long expired) - in the mid-1980's a fellow ham and I drove his lemon yellow Vista wagon (think "That 70's Show") to Ohio, which was the closest place to buy legal fireworks at the time. We picked up an entire car full of commercial-grade ones (packed to above the window lines), put some blankets over them and drove back to New Jersey. Just after crossing the Delaware River back into NJ, the car conked out (again, think "That 70's Show"). We had a bag phone and called for a tow to bring us the whole 60 miles back to Wyckoff, NJ. We kept getting "helpful" police pulling over and asking us if we needed help, and we were "Nope - all good - called for a tow" and showed them (newfangled at the time) Mobira bag phone to distract them.
The tow truck finally came and brought us to Wyckoff. We paid the tow truck driver and let him take whatever he wanted of the fireworks as a tip.
We had enough to last several years. The second year, 2 friends and I went in a windowless van to see the official Holmdel (near Bell Labs) fireworks show. We thought the official show was pretty lame, and had a van full of fireworks, so... we set up our own show behind the bleachers. The people putting on the official show began to notice that people in the bleachers were looking behind the bleachers at our better show, and eventually some burly guards came strolling over. We packed up everything into the van and took off back to the house in Holmdel. As we were driving away, I remarked to my two friends that "I just realized I've become the person my parents warned me about".
