Replying to There is a hidden cave at my school

My friends found it last week under one of the campus streets, there are stairs leading down to this big-ass cavern. I don't know how this kid found it because the entrance it's pretty tricky to find. i've seen the entrance but haven't been down there yet, but apparently everyone who has found it in the time (the schools 180 years old) it's been around has inscribed their name on the wall, so we're gonna do that next time we get the chance. So hopefully no one else finds it and we can hang out there between classes and shit. Anyone else have a similar place?
