I found someone’s driver’s license on the floor of the hotel where I work. How can I get in touch with him so he can pick it up? Can you use somebody’s license number to look up their cellphone number?

I went to a party, and rather than drive drunk, I just climbed into the back seat of my car and had a snooze. When I told my mom, she asked if I had the windows up and freaked out when I said yes. Her worry is that I could have suffocated. Is it really dangerous to sleep in a car with the windows rolled up?

I want to do a cross-country trip to all the best diners in America, but I’m not the best at following maps or directions. Can you tell me which states don’t allow u-turns?
