Report 4637: Family hears late night vocalizations near Lake McCumber

It was about 3AM at Lake McCumber, California. I was with my mom, aunt and uncle, and my uncles son and daughter in law. My uncle and his son stayed up all night listening to the strange noise that was somewhere in the meadow. They had no idea of what animal it was, I did. I had heard this noise before. I woke up my mom who didn't want to hear it at all. I bet that the nieghbors across the meadow seen the creature, or at least heard it more clearer than us. This event happened June 26th of 2002.
