Hehe. I am an ex truck driver. Been there. Done that!

It got to the point that I could plan most routes without even looking at my road atlas. I have run I-80 from the San Francisco area to where it dead ends on I-95 just before you cross from NJ to NYC. I have run I-40 from California to NC. I-10 from California to Florida. I-35 from Minneapolis to Laredo, TX. I-95 from Maine to Florida.
