How can you get lost on a circular freeway? Easy. Other large cities have a natural barrier such as an ocean or mountain. In Chicago, you can go east only as far as Lake Michigan. The Atlantic gets in your way in Boston, Baltimore and Miami. Seattle has Puget Sound or Mount Rainier, and San Francisco has the bay. But in Houston, you have a whole lotta flat and not a whole lot more. In Los Angeles, if you're lost but see the Pacific, you just turn your car around and head back the other way. But woe is unto the fresh transplant to our fine city who finds himself lost on the 610 Loop. There is no beginning and no end. You just go round and round. For those not in the know, directions like North Loop East and West Loop South are a good enough reason to get a cellular phone, a compass and a stress appointment with a therapist.
