Channeling my inner Xu Zhimo for a day in Cambridge, only to get lost at the Mathematical Bridge!.

Never trust your GPS in Cambridge, because the streets here are paved with a mix of "cobblestones and maze logic." First off, rent a bike—it's the standard local gear. Otherwise, you'll realize walking will never let you catch up with those gown-wearing, sprinting overachievers. You definitely have to go punting and listen to the guides drop fun facts like "Newton's apple tree is actually fake." Then there's the famous Mathematical Bridge; rumor has it that once taken apart, it can't be put back together. I strongly advise against trying to prove this—tuition isn't cheap. Around noon, head over to Market Square, grab some fish and chips, and crouch on a street corner pretending to ponder the philosophy of life. Just remember to steer clear of the professors zooming by on their bikes ten times faster than you. Their heads are full of the theory of relativity, and traffic lights don't exist in their world. In the evening, grab a beer by the River Cam and watch the sunset turn King's College golden. I guess this is what they call "British melancholy"! Cambridge University
