Happy Independence Day! As we celebrate our 236th birthday as a nation, you might not see as many fireworks light up the sky this evening. The long stretch of hot, dry weather we’re experiencing is forcing many local authorities to postpone their fireworks displays. For fireworks retailers, the season has been a good news, bad news story. Some vendors are seeing the weather bite into their revenues, but they’re also reveling in a new state law that allows them to sell more pyrotechnics than ever before.
