WestEastNorthSouth

So, I got lost. I'm a self-claimed "http://maps.google.com/" nerd.
I normally won't get lost because I carefully check directions wherever I go.

Today, I decided to be spontaneous. What did it bring to me? Getting lost.
I-95, I-83, I-70, I-695, I-795, and I-895 are the major interstates around here.
Then the list goes on with other numbered streets like 40.

It's already too confusing to think of East and West and North and South.
What is the difference between I-695, I-795, and I-895!?

Anyway, I drove an extra 40 miles to get home.
I guess it gave me a different type of a lesson.
