A little car guy stuff.

 I'm on a long road trip today. Driving between Chicago and Indianapolis I was pulled over by a cop for suspicion of drunk driving. It was about 6 o'clock PM. Why having a hard time keeping my car between the lines. I was wondering because I was fighting pretty hard and wondered if I needed ball joints or something. That's a similar experience I have had with my pickup. I like to run my tire pressure a little bit high in order to get better gas mileage. The spec is 30 pounds but I usually run about 37. Its fine but on the highway it wanders all over the place. This morning I took five pounds off each front tire. No its behaving perfectly stays inside the line doesn't wander and feels solid
