Please be aware that a company called "couchsurfing.com" does not care if the people they place in your homes are hard drug users and a danger to your children. A friend of mine reported someone who has documented gang ties and hard drug use and couchsurfing.com still allows this person to be a member and search for places to live through their service. They do not care about the safety of your home and your children. Please do not use the services of "couchsurfing.com"
