 said the first hydrant party at Sioux Park was a huge success. It was a hot day, there were a lot of kids, and it's a lot of fun and water to go around. Last summer's hydrant party at College Park was a big success, so we're hoping for another great turnout. We're again encouraging kids to bring their squirt guns and other water toys from home. As the summer warms up, these parties will be a great way to cool off. In case of inclement weather, the event will be canceled. Check for updates on the Rapid City Parks and Recreation Facebook page.
