Knox Fun Day & Fireworks
I don't know what's still on and what isn't tonight. Best thing I can tell you is to check locally,
2019 City of Knox Family Fun Day & Fireworks includes the Independence Day parade which starts at 1pm. The park opens at 2pm and there will be lots of family fun activities until the fireworks at dusk (roughly 9:30pm)
