One more caution to them: at trucks stops we have been approached by people wanting money. Tell them to ignore the person and keep walking! These people have sad sob stories about a sick mother and needing gas money to get home. One of the best answers to that was from this forum. The forum member told the person they were very concerned about their plight and pulled out their cell phone and pretended to call the police to help the person. The person hopped in their car and sped off!! Again, use their heads and don't talk to strangers.
