These were taken at the High School in Montgomery Township, NJ. We've attended the Montgomery Township 4th of July fireworks for about 10 years. We've been doing it since the kids were in kindergarten (and before I knew how to use a DSLR). Initially, the fireworks were at the Orchard Hill Elementary School due to a worsening economy the township government decided that taxpayer money should be spent on school and not entertainment and cut the firework budget. The local business community and residents came together and formed a firework committee. The entire affair is now 100% community supported.
The firework event is often well attended and is funded independently of the township.
