Doesn't help in California because people buy them in Nevada and resell them. Apparently that's easier to do nowadays due to the Internet?

> Despite strict fireworks bans in many cities, including Oakland, they’ve become a year-round nuisance in the Bay Area. And one of the primary ways they’re spread is through the enterprising but illegal work of small-time dealers who obtain the contraband from licensed shops outside of California, sneak it into the state, and then sell hundreds and even thousands of pounds of explosives out of homes, vehicles, storage units, and even corner stores.
In a lot of states, Indian reservations can also sell them. And they’re basically completely unregulated. It’s illegal to bring them or set them off into other towns but people do it. Hundreds of people. And tens of thousands have to be repeatedly woken up because of their selfishness.
When I was in North Carolina on a trip the chap I was visiting said I'd know if I was crossing over to South Carolina when I saw all the fireworks shops as it was illegal to sell them in NC but not SC. Funny to see.
(No idea what the actual rules are, just repeating what he told me)
