Leesburg Independence Day Parade, Concert, and Fireworks
This is the classic county-seat July 4 if you want the full day: parade in the morning, then food, music, and the big Ida Lee fireworks show at night. It is also the highest-friction plan because heat, parking, and crowds will all matter, so build in more time than you think you need.
King Street closes to through traffic at 9:30 AM and reopens around noon. Coolers and large bags are allowed at Ida Lee but checked at gate entrances. Pets, alcohol, glass bottles, and personal fireworks are not permitted.
