Comprehension Dawns
I moved from Baltimore to Raleigh 2 1/2 years ago, and ever since the local road system has seemed off somehow. I finally figured out why: the main east-west routes in Baltimore are U.S. 40 and I-70, while in Raleigh they are I-40 and U.S. 70. I wonder how many other pairs of cities have a similar reciprocal correspondence.
