there are several other homes with tunnels near the playboy mansion. i am racking my brain trying to remember the streets they were on but it was quite a while ago when i lived by these scumbags. i went to several parties in my younger days and these creeps would show off the tunnels to us young teenage girls. i thank God everyday that i didnt disappear in one. im going to look on Google earth and see if any houses jog my memory. also there is a quarry (not used since 2012ish) right across the freeway from my house and i bet it has underground tunnels too
