I live in Yucaipa, and in high school when we were bored we would head down to Redlands and drive around and what not. and few friends and I got into the habit of going to prospect park and other "haunted" places. I swear this story is completely 100% true with no fabrication what-so-ever.
Just a random night meeting up with a few friends, deciding on what to do. A friend suggested bowling, so Empire Bowl it was. By this time we'd met up with some girls, and of course, we boys began talking about "scary" places to go. Wouldn't you know it about 10 of us rolled up to hillside.
