 With the latest from the KOTA Radio Newsroom, I'm Derek Cade. The second in a series of three hydrant block parties is scheduled for this Wednesday, July 10th at College Park from 1 to 3 p.m. The hydrant parties are free and hosted by the Rapid City Parks and Recreations Department and supported by several city departments. The events are open to all ages with fire department personnel turning on the fire truck hoses to get participants wet.
