 The City Fireworks Show featured around 1,000 fireworks and 250 drones. There is a Code Red extreme heat alert through Saturday, and that has forced Rec and Park officials to shift to new schedule. Park pools will be open from 11 to 8.30. Neighborhood pools open from noon to 7. Druid Hill Pool will close early tomorrow, but that's because the city is hosting its first pool party for teens. That pool party kicks off at 6 o'clock tonight at the Druid Hill Park Pool, says Josiah Smith with Baltimore City Rec and Parks.
