Road Trip!

I've come to the conclusion recently that a person should not take long road trips with other people that do not converse very well.
On a four hour trip, with less than 20 minutes of shared conversation the entire time does NOT make for an enjoyable time. So if you know you're going to be going somewhere, my advice is too choose companions that you know you can be comfortable with on your journey.
Choose someone you know you have something in common with that can be the basis of a conversation. Pick companions that won't sleep the whole time and make things boring. Someone that you can point out interesting sights on the side of the road to. Someone that will help you navigate if you get lost and someone that can help you keep an eye on the road.
Unless you feel comfortable being on the road by yourself or in a car full of strangers, take careful consideration when deciding who you drive with.
