This is nothing new. Every website in this genre has one of these. If you choose to go explore any abandoned place, you are most likely trespassing which is very illegal. If you get caught on private property, you can potentially be arrested and fined. Do this at your own risk. Besides any legal problems you may face, you are exposing yourself to lung disease and cancer risks such as asbestos and lead paint. Asbestos is known to be a leading cause for many diseases, so take this into consideration. If you want more information on asbestos, I suggest you go here The Environmental Protection Agency Website. Many of these places are also old and deteriorating. You are taking the risk of falling through floors, roofs, or things falling on you. Nobody other than yourself will be held responsible for your actions.
