Gunfire In South County Regional Park?

Early this morning, perhaps from 6 – 7:20 am, we heard approximately 15 shots that seemed to come from South County Regional Park, in groups of 3-5 rounds.
We’re not sure what that was. It was not enough for any kind of target shooting competition. Maybe the golf course is trying to take out some kind of nuisance animals, like geese?
We’d love to hear from locals. If anyone knows what those sounds were, please post a comment, or send us an e-mail.
